Without having tested explicitly, it looks like the default case for

Don't think so (run on my F-16 machine, without passing any options to
that effect):

checking for entropy source... /dev/urandom

If you look at the test, it has:
---------------
for f in /dev/arandom /dev/urandom /dev/random; do

So, non-blocking is preferred on Linux for sure.
That's good -- I guess the question is what happens if /dev/random
is chosen, though, either automagically or through an explicit choice
with --with-devrandom=/dev/random.
In the latter case, at least, I suppose it might be acceptable for
apr_hash_make() blocks, since you picked /dev/random and presumably
know what you're doing.
