like kutner, the plumber decided to off itself for
seemingly inscrutable reasons this morning.

the abort condition does not appear to hold:
	if(t > s+n)
		abort();
since 0x3a497 < 0x3a430+0x93 and also
a!= nil, as would be required.

the interesting thing that happened at the
time was that one of plumber's clients was
off in the weeds waiting for something to
happen.

ideas?
