Doesn't change anything.  Upon returning from the suspend, the screen is
blanked and remains blank no matter what you do.

Interesting... doesn't work as it should, but does something different.
It *MAJORLY* messes up keyboard handling.  Returning from a suspend
doesn't clear the screen as before, but leaves up the command line and
such.  When you type a command key, the key is displayed and requires a
return for confirmation at which time both the key AND the following
return are acted upon.  Hitting ^L will display "^L" on the screen.
Hitting return immediately afterward will refresh the screen and select
the current link.  Hmm...  the signal handling for SIGTSTP appears to be a
likely candidate. :)
