BASH PATCH REPORT
=================
Bash-Release: 5.0
Patch-ID: bash50-004
Bug-Reported-by: Daniel Kahn Gillmor <dkg@fifthhorseman.net>
Bug-Reference-ID: <87lg0g8aiw.fsf@fifthhorseman.net>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2019-04/msg00076.html
Bug-Description:
In bash-5.0, the `wait' builtin without arguments waits for all children of the
shell. This includes children it `inherited' at shell invocation time. This
patch modifies the behavior to not wait for these inherited children, some
of which might be long-lived.
Patch (apply with `patch -p0'):
