    VKERNEL - Fix entry into ddb when running a SMP vkernel.  Fixes stop/cont
    
    The vkernel was trying to send individual LWPs a SIGSTOP, but POSIX handles
    SIGSTOP differently from other signals and it was not having the desired
    effect.
    
    Instead the vkernel now sends SIGXCPU to each individual LWP and installs
    a signal handler to pause the thread until the debugger wishes to wake it up
    again.
