Allegro doesn't use nearptrs, except for the VBE/AF driver (which
requires them due to a badly-thought-out part of the VBE/AF standard).

The default sbrk algorithm could have something to do with the problem,
though. If NT can only be used with the unix sbrk, that pretty much
rules out anything that traps hardware interrupts! Argh...
