All multiplex servers must have access to the pre-filter and term-breaker external libraries.
Users must ensure that each external pre-filter and term-breaker library is copied to the machine hosting a multiplex server and placed in a location where the server is able to load the library.
Each multiplex server works independently of other servers when calling the external pre-filter and term-breaker. Each process space can have the external libraries loaded and perform its own executions. It is assumed that the implementation of the pre-filter and term-breaker functions is the same on each server and will return the same result.
Unloading an external library from one server process space does not unload the library from other server process spaces.
