could you provide the output of 'pkg_info -E linux_dist\*' please?

thanks.

btw: i also experience the problem. newer versions of linux_dist come with
linux binaries that make heavy use of futextes (even 'ls'). you should see
a lot of futex warnings in 'dmesg -a'.

i believe the issue is with FUTEX_WAIT_BITSET. since it isn't that different
from FUTEX_WAIT (which is already implemented), i've started to implement it.
however i don't have a lot of time atm unfortunately.
