Is your shared library used simultaneously by multiple threads ?

The consensus seems to be that if you want multiple concurrent threads
to use your library, implement a mutex protected queue which allows a
caller to submit a request and block until the request is satisfied by a
single libwww thread or times out.  I do not know of a published source
for such an example.  The version I had done was part of a larger "work
for hire" and not my own to redistribute.  Perhaps we could implement a
"clean room" version using pthread.h and add it as an example.
