描述

For unixes at least, I suspect it would be easier to implement a correct delegation for Tool::exec by using a Unix exec call. But this is an area I need to dig into more. (Expert advice welcome!)

研究方向
Investigate how to implement Tool::exec using the Unix exec system call in Rust. Review the current implementation of Tool::exec in the codebase (likely in src/tool.rs or similar). The issue mentions that using exec could simplify correctness. Look at how other Rust projects handle subprocess execution with exec, and consider edge cases like error handling and cross platform compatibility. There may be existing discussions in the two comments on the issue.
