Detailed Description

Routines to manage threads.

Author

Olivier Hureau, Hugo Feydel , Julien ALaimo

There are four main operations: Fork – create a thread to run a procedure concurrently with the caller (this is done in two steps – first allocate the Thread object, then call Fork on it) Finish – called when the forked procedure finishes, to clean up Yield – relinquish control over the CPU to another ready thread Sleep – relinquish control over the CPU, but thread is now blocked. In other words, it will not run again, until explicitly put back on the ready queue.
