Description Zac Medico gentoo-dev 2023-10-17 18:39:55 UTC 
Eventually, fd_pipes can be supported by ForkProcess (bug 915896). However, there's no need for the MergeProcess elog and mtime pipes to be coupled to fd_pipes, so they should be decoupled from fd_pipes and use multiprocessing.Pipe to pass picklable connections as arguments to the target function.

    MergeProcess: Use multiprocessing.Pipe to decouple fd_pipes
    
    Use multiprocessing.Pipe to decouple from the fd_pipes implementation
    since that currently only works for the multiprocessing "fork" start
    method.
