Hi, I like using boost threads, but I'm currently working on a project 
where I need to access the private handle to the underlying system 
thread (in the cases I'm concerned about, the pthread_t).  This is so 
that I can take advantage of platform-specific functionality, such as 
setting CPU affinity and (more generally) calling into other libraries 
that expect a pthread_t.  Is there any way to do get this handle?
Thanks!
class thread
{
public:
...
     typedef platform-specific-type native_handle_type;
     native_handle_type native_handle();
...
};
Hmm.  Looking at the source, this doesn't actually seem to be in

It's there for Win32 and not for pthreads. I'll add it for pthreads on trunk.

I see.
While you're at it, would you mind also adding it uniformly to all the 
other threading primitives (mutex, etc.)?
There isn't always a valid mapping (e.g. condition_variable_any, timed_mutex),
but I intend to add it where possible.
