a0threadsTotal...

Accounting on the number of threads.

Syntax

`extern int`	`athreadsTotal,`
	`athreadsBlockedComm,`
	`athreadsBlockedLock,`

Description

These three variables, readable by the user but updated only by Athapascan, reflect the current state of a node, regarding the number of (user) threads running (or waiting) on that node.

athreadsTotal is the total number of user threads on a node (threads are created by Remote Thread Creates, of by locally creating a slave).
athreadsBlockedComm is the number of user threads on a node blocked waiting for a communication to terminate.
athreadsBlockedLock is the number of user threads on a node blocked waiting for a lock (or anything that is not a wait for a communication to terminate).

BUG: the update of these variables in Athapascan is not protected, so their values might be erroneous, due to race conditions.
