Right, one of the key things to remember with manylinux1 is that it
is, *quite deliberately*, only an 80% solution to the cross-distro
lack-of-ABI-compatibility problem: we want to solve the simple cases
now, and then move on to figuring out how to solve the more complex
cases later (and applications that embed their own Python runtimes are
a whole world of pain, in more ways than one).

Since we know that extensions built against a statically linked
CPython will run correctly against a dynamically linked one, then it
probably makes sense to go down that path for the manylinux1 reference
build environment.

However, there's one particular test case we should investigate before
committing to that path: loading manylinux1 wheels built against a
statically linked CPython into a system httpd environment running the
system mod_wsgi. If I've understood the problem description correctly,
that *should* work, but if it doesn't, then it would represent a
significant compatibility concern.
