tracker does not use mmap (if we did the memory usage would be through 
the roof!)

qdbm uses mmap a little bit so there's not much we can do in tracker.

FWIW, qdbm seems to have options for mmap (or rather if it cant detect 
mmap installed it uses an alternate method)

so you will need to experiment with that - but also file bugs against 
fuse too!
