Since I just independently created another thread on the need for regex
allocators (Topic: interprocess allocators) and now see that this thread is also
active the same week, I suspect this issue arises not infrequently.

For the reasons given in the "interprocess allocators thread," the justification
for including allocators in regexes is IMO every bit as strong as for strings
and containers.
