This change is correct, but I think the commit message is a little 
unclear.  What you're really trying to avoid is using the kernel stack 
for waitset (because the kernel stack might get swapped out).  The 
unclear-ness comes from the fact that other memory allocators also give 
wired kernel memory, not just malloc().

Could you maybe clarify that in the log?
