linux: pid 8416 (gmake): linux_sys_futex: op FUTEX_WAIT_BITSET not 
implemented
linux: pid 8907 (ls): linux_sys_futex: op FUTEX_WAIT_BITSET not implemented
linux: pid 8908 (ls): linux_sys_futex: op FUTEX_WAIT_BITSET not implemented

yup.  got those.  I saw them before when everything was working though 
so I assumed they weren't the problem...  ls generates them but seems to 
work just fine.

I may try down porting linux_dist and seeing how that works...

Time seems to be a commodity in short supply for everyone.  I'm no 
kernel hacker, but I'm happy to test patches, etc.
