It's not feasible.  Every handle stored anywhere in the program would be
trash (think about it).

VM could conceivably be of help, but the Sys 7 implementation has the
charming feature of allowing FRAGMENTED virtual memory, a really stunning
concept.  If you have the MMU and the disk space, you can avoid the problem
by allocating a whopping big VM space, and then fragmentation, even if it
occurs, won't be a problem.
