Yes, it was.  This was years ago, so I don't remember details.
I think it was on Linux, but it might have been windows.

I didn't use storage pools.  I think I hacked the GNAT runtimes a little
bit.  E.g. change System.Memory to use GC_malloc, which is Boehm's
version of malloc.  And I had to change how tasks are created to
call Boehm's version of thread-create.

I don't think so, at least not in a simple way.  GC can't work within a
single pool -- it would need to trace pointers that point into the pool
from outside it (from other pools, from the stack, registers, ...).
