IIRC taking a snapshot with LVM/XFS takes just a few seconds. I guess
everything should continue after the snapshot. What do the cyrus processes
do if they receive SIGSTOP? Will they stop immediately or will they not
stop at all? I mean, if a process receives SIGSTOP while it writes to a
file, will the write finish before the process stops?
