I'm actively looking into this, as problems with mozilla are the most
frequently reported issues with the SA and pthread stuff. I'll post
here when I think I've made progress. The kern_lwp.c thing the other
day is unlikely to be the fix, unfortunately...

Also, the "sawait" state is a moderately normal state for one LWP in a
multithreaded process to be in; that essentially means that the
userland thread system thinks it's idle and is "parking" the last
running LWP in the kernel.
