This sounds like a possible solution. TPA doesn't matter in this case, because
it is freed when the process (running a shared text) exits. Fragmentation seems
to occur, when

1) running shared text
2) last process running shared text exits, shared text still hangs around.
3) allocating memory in eg, a device driver or fs or running TSR or daemon.
4) goto 1

After a few iterations the stuff allocated in 3) prevents the free shared
text regions from beeing joined together to one large hunk.

Sigh! Thats a real problem when physical address space == virtual address
space.
