This is all from mycroft:
...
Create macros (with names borrowed from Mach 3) to manipulate
object->paging_in_progress, and use them. When decreasing the
paging count, always make sure to wake up anyone waiting.
Fixes `vospgc', `vosca1', and `vosca2' hangs.

pathological behaviour (freezes) when running short of free pages. see
PR#2755 for a more detailed explanation (from jonathan).
thanks to john dyson for the first cut of this change.
