Subject: sys V.3.2 swap problem: unterminated sleep?

In the vanilla 3b2 sources for system V.3.2, in file os/swapalloc.c,
a process can go to sleep waiting for more swap space with this line:

	sleep(&swapwold, PMEM);

However, there doesn't seem to be a corresponding wakeup.
We have systems that lock up just after printing the "DANGER: Out of
swap space." message that precedes this sleep.

Is this really a bug, or am I misinterpreting?
If it's a bug, has someone already fixed this?  I'd be delighted not to
reinvent this wheel.
