This is one of those wacky Mach system calls.
ftp://ftp.netbsd.org/pub/NetBSD-current/src/sys/compat/osf1/README.mach-traps 
spells out the problem.

In general, apps which are linked to libpthreads.so or libpthread.so
tend to use mach system calls.  Luckily, not many intersting apps are.
Acroread is the only productivity app I've found so far which is.
