Huh!  Indeed!  The condition "gpm < 0" is encountered all the time, so
my patch ends up turning gpm off right away.  But now I'm lost: I don't
understand what delete_gpm_wait_descriptor and add_gpm_wait_descriptor
do, because if I remove the call to add_gpm_wait_descriptor, the gpm
support seems to still work just fine.

Nick, do you have an idea what's going on?
