Up – infer » IBase__ProcessPoolModule IBase__ProcessPool Pool of parallel workers that can both receive tasks from the master process and start doing tasks on their own. Unix pipes are used for communication, all while refreshing a task bar periodically.
Due to ondemand analysis, workers may do tasks unprompted (eg, when analysing a procedure, a process will typically end up analysing all its callees). Thus, children need to update the main process (which is in charge of the task bar) whenever they start analysing a new procedure, and whenever they resume analysing a previous procedure. This is more complicated than what, eg, `ParMap` can handle because of the bidirectional flow between children and parents.
The children send "Ready" or "I'm working on task <some string>" messages that are used to respectively send them more tasks ("Do x") or update the task bar with the description provided by the child.
