    Test suite: use Process.wait() instead of IO#close() for subprocesses. · 2266efd2
    anonym authored
    IO#close() seems entirely wrong here, and very likely is the cause for
    our defunct subprocesses; I thought IO#close() did an implicit
    Process.wait(), but it seems to actually just flush buffers and
    forcefully close immediately, even if the process has not exited yet.
    If this commit fixes our issues I'll do a pass through our other uses
    of IO#close() for subprocesses and fix them too.
    Will-fix: #17551
