274-276: LGTM! Clear and accurate comment explaining the zombie process prevention.

The updated comment effectively explains the purpose of the goroutine: it monitors stdin to detect when the parent process dies, ensuring proper cleanup of child processes. This is a crucial mechanism for process management.

Let's verify the implementation matches the comment's intent:

✅ Verification successful

Comment accurately reflects the implementation

The verification confirms that:

1. The stdin monitoring pattern is implemented exactly as described in the comment
2. The goroutine reads from stdin and exits when the parent process dies (detected via read error)
3. This is the only instance of this pattern in the codebase, ensuring consistent documentation

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the goroutine implementation is consistent across the codebase
# and there are no similar patterns that might need the same clarification

# Test: Search for similar stdin monitoring patterns
rg -A 5 'os\.Stdin\.Read'

# Test: Search for other zombie process prevention patterns
ast-grep --pattern 'go func() {
  $$$
  os.Stdin.Read($_)
  $$$
}'

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
