[PATCH 0/3] gdbstub: Protect gdb_handlesig() with EXCLUSIVE_GUARD()

[Ilya Leoshkevich]

Hi,

I ran into the issue with only one thread being stopped on a
breakpoint hit [1] again [2]. While a proper solution to this includes
kicking all threads using a reserved host signal and parking them, and
is partially in review and partially in the works, this small series
resolves most of the problems that occur during a typical debugging
session. Furthermore, it is a subset of the ultimate solution and
therefore would not have to be reverted.

Best regards,
Ilya
