Perl module to resynchronize multiple control flows

Async::Mergepoint is a module designed to provide a way to resynchronize multiple parallel control flows. Often in program logic, multiple different steps need to be taken that are independent of each other, but their total result is needed before the next step can be taken. In synchronous code, the usual approach is to do them sequentially.

An asynchronous or event-based program could do this, but if each step involves some IO idle time, better overall performance can often be gained by running the steps in parallel. A Async::MergePoint object can then be used to wait for all of the steps to complete, before passing the combined result of each step on to the next stage.
