Does araneida support multithreading or not :
Acc to http://www.cliki.net/araneida it does :
Works with or without multiple threads (depending on the lisp
implementation). In single-threaded mode, hooks into the event loop so
that you still have the top-level available while it listens for
connections.
Acc to araneida's doc in ver 0.9 in dir doc/index.html features/non-
features:
Does not use multiple threads. Hooks into the SBCL/CMUCL event loop so
for many purposes it behaves as though it does.
