I've tracked this one down.  It happens because input/linux_kbd/input.c
calls ggRegisterCleanup(), which calls register_sighandler(), which
calls signal() on the SWITCHSIG setup by display/linvtswitch/visual.c,
and this causes the behaviour to become SA_RESETHAND, thus linvtswitch's
signal handler is set to SIG_DFL after the VT_PROCESS release signal
comes in, thus causing the acquire signal to kill the program.

AAAAAAARRRRRRRRRGGGGGGGHHHHHHHHH  !

The solution is not to use signal() but always use sigaction().  Marcus,
could you please fix that ?  Thanks heaps !

Cheers,
