Cannot you? From reading the posix thread documentation I have an 
impression that you can.

See for instance
http://www.opengroup.org/onlinepubs/009695399/functions/pthread_join.html

It says:

 > The pthread_join() or pthread_detach() function should eventually be 
called for every thread that is created with the detachstate attribute 
set to PTHREAD_CREATE_JOINABLE so that storage associated with the 
thread may be reclaimed.


Moreover, there is also a thread return status PTHREAD_CANCELED that is 
returned by pthread_join when the thread exits due to pthread_cancel 
request. See the paragraph "Thread Cancellation Cleanup Handlers" at 
http://www.opengroup.org/onlinepubs/000095399/functions/xsh_chap02_09.html
