after further investigation this resulted to be a wrong assumption on my
part, the pollset pointer inside the opaque apr_pollset_t structure is
indeed NULL in 0.9, but considering that it is opaque anyway, its status
shouldn't matter and therefore this should be instead considered just as
undocumented behaviour then.
