Message:

Major release: Change the task model to implement the POSIX threads API.

• The shell "exec" and "kill" commands can be used to activate/de-activate the applications.
• The "pause", "resume", and "context" commands can be used to stop, restart, a single thtead or to display the thread context.

This version has been tested on the following multi-threaded applications,
that have been modified to use the POSIX threads:

• classif
• convol
• transpose
• gameoflife
• raycast
