Debugger under Solaris

[Robert Lunnon]

I need some help to implement the debugger under Solaris. In particular I need 
help with how ptrace interacts with the threading model under Linux which I 
understand uses processes for threads. Since Solaris has user mode threads, 
stopping a pid stops all the threads in the debugee which used to deadlock 
the debugger. This suggests I need to operate on threads within processes 
rather than the processes themselves. This is possible with a few IPC tricks, 
but I need to understand the semantics

Any volunteers ?
