I was thinking something a little ridiculous like 10K or 64K.

Assuming the usage you care about is something like hibernate on a
machine with disjoint memory where you truly need one segment for
each memory region.

The only point of a limit at all once we introduce dynamic allocation
is to catch buggy apps.
