Hmm. To verify, I just ran it on a PPro 150, 2.2-STABLE circa 
Oct 1st:
fcntl: 13.9273 secs
ipc: 11.8795 secs

On a PPro 200, 2.2.5-STABLE from today:
fcntl: 10.9368 secs
ipc: 9.40272 secs

Now for the interesting part, a Pentium 166MMX:
fcntl: 9.64589
ipc: 7.66043

Could it be a weird PPro thing? The only other difference in the
166 kernel is that the FASTER_5X86_FPU (something like that)
is turned on. Oh yeah, the kernel is 2.2.5-STABLE from today as well.

I'll see if I have an older machine/kernel around and try out some
more tests..
