That depends.  It could be that Applixware itself is doing lots of mallocs
and frees, maybe using an mmap-based allocator.  This can fragment the
VM map for that process.

UVM doesn't currently collapse adjacent VM map entries .... partially
because doing that is also expensive ... Although, a clever implementation
could take hints about where to begin and end the collapse... chalk one
up on the TODO list...

Of course, this may not be the root cause of your problem.  I'm just throwing
out ideas :-)
