Minor issue with MogileFS/Worker/Monitor.pm

[dormando]

Fwiw, my only complaint on this tiny patch (aside from being incredibly 
nitpicky) is this:

-    my $num = int(rand 10000);  # this was "$$-$now" before, but we 
don't yet have a cleaner in mogstored for these files
+    my $num = "$$-$now";

I'd prefer to leave the line alone in case of delete suddenly failing on 
someone and prevent the disk from filling up. Unless, of course, there 
are complaints.

Also adds a teeny bit of load, but it's oh so teeny...

(yes, I'm reviewing patches again. Sorry for the huge stack that's built 
up, we'll get through them as soon as we can).
