Following a summer quest for figuring out a pesky thread issue with Rust, a fix has been merged into the BeOS-inspired Haiku kernel for one less patch to worry about with getting this popular programming language running well.

Developer nielx spent quite a bit of time this summer investigating "failed to join thread: No such process" errors when compiling Cargo and failed test cases.

The issue was resolved in the Haiku kernel by removing a limit on the number of dead threads in a team.

Thus with the latest Haiku kernel, a workaround is no longer needed for the Rust standard library. A number of other discoveries were also made along the way.
