Because mmap won't work on HP-UX (yes, it still performs well enough
with BDB, even though skiplist is useless without mmap). Maybe if Cyrus was
modified to access the memory mapped files _exclusively_ through mmap()
and not write them directly using file I/O in the same time, HP-UX would
be happy with mmap.

What does it hurt to keep it there? As far as I can see, that part
of the code base hasn't been touched much in years. Maybe add a
bit more explicit docs for those that might inadvertently use it...
