It shouldn't be a problem, other than requiring both runtimes to be
present. Unless you use PQtrace() in which case it will be a big
problem.

Basically, as long as you don't free() something in one runtime that
was malloced():d in a nother one, and as long as you don't pass "CRT
pointers" between the two runtimes, you are fine. And we do pass a CRT
pointer around in PQtrace, but that's the only case. We used to have a
problem with some Kerberos structure that was malloced in one place and
free()d in another, but that has been fixed.
