Hmm, did you actually try this?  I just did, and it worked like a charm.
I.e. both the main program and the dlopen()ed library function used the
same __sF[].

That's correct, but for different reasons: the dlopen()ed library may
call
functions from libc that aren't linked into the main binary and can only
be
resolved from the dynamic libc.
