Interesting.  Thanks.

I think 16 is a bit too much.

The Linux man page says that pthread_t might be a struct.

What OS are you running on?  I think Linux uses a whole process for each 
thread.  If you are running on Linux, try using gettid() rather than 
getpid().  That shouldn't take any extra space on the printed line.  
(Well, an extra space if the value of the ID grows by a digit when 
printed.)
