I would bet on a massive threads creating/deleting testcase signalling tasks
around, together with watchpoints.  There are races in the linux-nat code and
IIRC even gdbserver code.

OTOH if one tries hard one can probably manage one day to fix all the corner
cases in the ptrace based linux-nat and gdbserver.
