in thread IPC::MPS - Message Passing Style of Inter-process communication

IPC::MPS port is other process, but not subroutine.

Consequently, IPC::MPS is better to use with the blocking system calls and while working with the databases.

Simple:

IPC::MPS - only select required. IPC::MPS::EV - EV. IPC::MPS::Event - Event.
