This is the default dispatcher that ships with GuildenStern. Use it by importing guildenstern/dispatcher and then starting a server's dispatcher thread by calling start.

This dispatcher spawns a thread from a server-specific threadpool for every incoming read request. The threadpool size can be set in the start procedure. Dispatcher avoids excessive thread swapping by not spawning a thread when activethreadcount has reached maxactivethreadcount. However, if a thread reports itself as inactive (by calling server's suspend procedure), another thread is allowed to run. This keeps the server serving even when there are more threads waiting for I/O than the maxactivethreadcount. This design seems to deliver decent performance without leaning to more complex asynchronous concurrency techniques.
