Subject: Do a small msleep() in the sig_int() handler before shutting down.
X-Git-Url: https://mattmccutchen.net/rsync/rsync.git/commitdiff_plain/d5a0b483797359517de787c33f518a4c804041f4

Do a small msleep() in the sig_int() handler before shutting down.
This kluge allows things like SIGINT to find our children before
we go throwing around SIGUSR1's at them.
