clisp proposal for google summer of code

[Sam Steingold]

Here is a proposal for the Google Summer Of Code program:

For <a href="http://clisp.org";>GNU CLISP</a>:
<strong>Finish the multithreading interface.</strong>
Most of the work has already been done by the project developers.
The only major thing left to be implemented are thread safe hash tables.
Since hash tables are used internally in CLOS, it is not viable to make
them lockable.
The current implementation should be replaced with lock-free
open-addressing ones like described here:
http://www.azulsystems.com/events/javaone_2007/2007_LockFreeHash.pdf
The hardest part in this reimplementation is integration with GC
because of weak relations.
For more information see doc/multithread.txt in the CLISP source
distribution.

Mentors:
          Vladimir Tzankov
