I was told the twe in FBSD 4 was not PAE 'safe'. Unless DFLY ported over the 
twe from FBSD 5, I assumed its current twe had the same issue.

This PAE feature just brought back bad memory of the 286 UNIX V. I may be 
able to last till the 64Bit OS ready if I don't have to allocate addition to 
the 500Mb dirhash. Is anyone thinking about a disk base indexed directory 
structure for DLFY?
