                             BASH PATCH REPORT
                             =================

Bash-Release:   5.0
Patch-ID:       bash50-004

Bug-Reported-by:        Daniel Kahn Gillmor <address@hidden>
Bug-Reference-ID:       <address@hidden>

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'):
