Thanks for the analysis! I modified the testcase to prevent those 
threads from exitting and fixed the weird identation (i messed it up 
when copying from another source probably).

But, there still seems to be something odd here. When the number of 
threads is greater than the number of available hardware watchpoints, 
GDB still seems to miss watchpoint hits.

I'm currently trying to narrow this down.
