Libumem uses a *lot* more memory than the standard allocator.  See the 
various man pages (man `man -k umem`), and the original "Slab" allocator 
paper for lots of details.

And don't rely on nagios or the like to spot the sort of transient 
memory spike that can be caused by bacula-fd, you need to crank it up to 
look every few seconds.
