Depends heavily on hardware. 386 clone running microport V.3 with 8M
of memory took 40 seconds to load up emacs, sticky bit saved 10-20
secs.  With single user it may be worth it.  Low speed is probably due
to stupid non-buffering controller, I'm now testing 1:1 interleave
controller and it really speeds things up, emacs loads in 10 secs
instead of that 40... with same hard disk. PC:s, you know ;-)

System V does very bad job of keeping disks unfragmented. Fsanalyze
told me that I had my CT miniframe emacs (~550k) in 400 fragments :-)
