Hi
I want to use pre-xfer exec function in rsync for permition checking. In my
Linux boxes, it successed. But today, I tried to put them in my FreeBSD box, it
failed.
I've checked the log, but found the pre-xfer exec returns always be -1,
which means waitpid failed to get the return status. After doing a little ugly
patch for the wait_process function as follow, pre-xfer works again.

Another method that fixes the problem is to set SA_RESTART to all the
signal handle functions. But I'm not sure if the above methods will bring other
problems to the program. So I'm asking help here. Does anybody has a better
solution ?
