std: Move a process test out of libstd - #62183
Merged

Conversation
This commit moves a test out of libstd which is causing deadlocks on musl on CI. Looks like the recent update in musl versions brings in some internal updates to musl which makes `setgid` and `setuid` invalid to call after a `fork` in a multithreaded program. The issue seen here is that the child thread was attempting to grab a lock held by a nonexistent thread, meaning that the child process simply deadlocked causing the whole test to deadlock. This commit moves the test to its own file with no threads which should work.

That is true, yes, but I don't really want to get in the business of fixing all platforms everywhere. At some point we just need our CI to work, and that's what this does. |

Fair. Is there an issue tracking this? Or don't we track such issues in the rustc repo? |

There is not currently, no, since it appears musl doesn't have an issue tracker, just a mailing list. |

@alexcrichton musl patch sent upstream: https://www.openwall.com/lists/musl/2019/07/01/2. I think a new release is planned to be out soon, or you can take the patch. |
