tcl-mq: POSIX Message Queues for Tcl. (Tcl package)

This is an announcement for a relatively new Tcl project: tcl-mp

Tcl-mp is a Tcl interface to POSIX Message Queues*. It provides a Tcl 
package that allows scripts to create/open/close/unlink multiple 
parallel message queues, and to send/receive messages synchronously and 
asynchronously to/from them.

* A POSIX message queue is an Inter-Process Communication mechanism 
available on Linux and some other POSIX-compliant operating systems.  It 
  allows to  or more processes (or threads) to communicate under the 
same OS. The messages are buffered by the kernel, which gives them 
kernel persistency. A message queue can be thought of as a linked list 
of messages. Threads with adequate permission can put messages onto the 
queue, and threads with adequuate permission can remove messages from 
the queue. Each message is assigned a priority by the sender, and the 
oldest message of highest priority is always retrieved first. Unlike 
PIPES and FIFOS, no requirement exists that someone be waiting for a 
message to arrive on a queue, before some  process  writes  a  message 
to that queue. It's not even a requirement for both processes to exist 
at the same time. Read mq_overview(7) for more details
