This happens when the inferior gets a signal at the same time we are trying to
interrupt it. If the signal is SIGSTOP or SIGINT, the interrupt machinery in
GDBRemoteCommunicationClient::SendContinuePacketAndWaitForResponse can mistake
the real signal stop for the maintenance stop and resume the process
incorrectly. RaiseTestCase.restart_bug_test reproduces this behavior. The bug
affect all targets which use the remote stub.
