 Doesn't help from the point of view of seeing which threads in GDB 
 match which debug output statements. On Linux this is easy as 
 pthread_t is a uint printed by gdb.
 
 How about getting gdb to print the pthread_t pointer address instead? 
 I don't care what the number is, so long as I can compare the thread 
 listing in gdb to the debug output and it makes sense!
 
 Cheers,
