Thanks for clarifying.  Would you mind explaining the "not possible in 
this testcase" part?  I do get spurious SIGTRAPs for the other threads 
from the "break 41 if arg != 5" breakpoint, reported as SIGTRAP (instead 
of as breakpoint hits).

Strangely enough, for the CRIS target (the above refers to CRISv32) I
*also* get breakpoint hits from "break 41 if arg != 5" for the other 
threads also (noticed by inspecting the remote communication), but these 
are ignored by GDB (neither displayed as breakpoint hits, nor as SIGTRAPs).

This is all when stepping without a lock, BTW.

Any insight as to what's going on is greatly appreciated.
