# Tests the case when gdb sends a character to gdbserver while
# the gdbserver was forced invoked just before.
# gdbserver must send a signal to itself that is wait-ed for by vgdb.
# But if this signal is masked, then vgdb does not recuperate the control
# and Valgrind dies. See function give_control_back_to_vgdb in m_gdbserver.c
