I think our use of threading would not be too timing critical, so we can
probably make it so that the user has to enable locking at run time (and we
use a function table for the locking functions resp. their dummies).

Otherwise two versions of the library seems to be ok, too.

It depends on what guarantees you want to make.  If you want to protect the
context as well, there is much more to be done.  If you require that one
context is not used by multiple threads at the same time, there is not too
much to do.

Thanks,
