From: Eric DeCosta <edecosta@xxxxxxxxxxxxx>
t7527-builtin-fsmonitor was leaking fsmonitor--daemon processes in some
cases.
Accomodate slight difference in the number of events generated on Linux.
On lower-powered systems, spin a little to give the daemon time
to respond to and log filesystem events.
