You are right. Perhaps for every command we send to FAM we should do
Ideally, this should be done by the FAM library itself. Or better, the library
should use nonblocking syscalls for communication with the server.
Deadlock races like this probably would not exist if event merging would be
done either by the kernel (enhanced dnotify) or the FAM server: i.e. a change
notification for some file should be sent at a maximum rate of 5 per second.
OTOH, if kfind watches 1000 dirs which all are removed with a "rm -rf *",
this will produce an event storm...
