Instead, it generates a pseudorandom serialno on request, ensuring that the
number selected is not -1 or the serialno of an existing logical bitstream.
NB. This inlines a simple linear congruential generator to avoid problems
of portability of rand() vs. the POSIX random()/initstate()/getstate(), and
in the case of rand() in order to avoid interfering with the random number
sequence. Adapated from a patch by Erik de Castro Lopo, July 2007.
