mask.
Since the exec family of functions does not reset the signal
disposition of signals set to SIG_IGN, nor does it reset the signal
mask, in order to be transparent, when spawning new child processes
to debug (with "run", etc.), we must reset signal actions and mask
back to what was originally inherited from gdb/gdbserver's parent,
just before execing the target program to debug. */
