Thanks, I don't understand what is special about gdb-mi that it's the
only one to trigger this problem, and I suspect there's a slightly
cleaner fix (as the above comment mentions, we only send ourselves
a SIGCHLD to work around problems we don't understand in some
undescribed situations, which may even be situations that don't exist
any more nowadays for all I know).
But I installed the patch anyway, with minor coding-convention cleanups
(wrap at 80 columns, space before open-paren).
