Hi,

I'm actually chasing a problem with GDB and hw watchpoints for embedded 
ppc targets.

If a thread X creates thread Y, is it expected that thread Y will 
inherit all the debug state from thread X? Including, for example, any 
hardware watchpoints/breakpoints that are set in thread X?

Thanks,
Luis
