I don't agree with the notes about Suspend/Resume. Suspending a thread on 
POSIX is possible, as long as you define what "suspending" means. Assuming 
a "suspended" thread is a thread that doesn't execute application code, 
forcing the target thread to wait on a mutex would be enough, IMHO (on a 
side note, this is how some third party extensions for Windows implement 
SIGSTOP semantics). Don't be too quick about dismissing "suspending" as 
"non-portable": condition variables and thread canceling were thought as 
*impossible* to implement on Win32, before RedHat successfully implemented 
the POSIX threads interface on Win32
