void MPE_Signals_call_debugger()
You may need to ignore some signals, depending on the signals that the MPICH and underlying communications code is using. You can do this in dbx by adding "'ignore signal-name'" to your .dbxinit file. For example, to ignore 'SIGUSR1', use "'ignore USR1'".
Currently, there is no Fortran interface for this routine.
