[nas] signal handling fixes for 2.6.2X

[Paul Fox <pgf@xxxxxxxxxxxxxxxxxxxx>]

i see that debian lenny is now using NAS 1.9.1.  does this
guarantee that it will make it into the next (after gutsy)
version of ubuntu?

i didn't pay much attention when jon and erik worked on it,
because it wasn't affecting me, but after upgrading to gutsy i
realized that the signal handling fixes that are in 1.9.1
(described below) are critical for newer kernels -- NAS is
unusable without these changes.

so if anything needs to be pushed to get 1.9.1 in play asap, we
(and i'm volunteering, if need be) should do that pushing.
