As does Yaws. The fact that a new process spawned by a request handler
process can't access the Yaws data stored in the request handler process's
dictionary sometimes comes up as an issue, but all in all it's not a
frequent problem. Still, Klacke or I will soon be adding a function to Yaws
to copy the necessary data into the process dictionary of a new process to
allow users to avoid this problem, but again, from what I've seen the
problem doesn't come up all that often in practice.
