[issue17374] Remove restriction against Semaphore having a negative value

[Raymond Hettinger]

Raymond Hettinger added the comment:

For reference, here is the Java API for a Semaphore ( http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/Semaphore.html ):

Semaphore
---------
public Semaphore(int permits)

Creates a Semaphore with the given number of permits and nonfair fairness setting.

Parameters:

permits - the initial number of permits available. This value may be negative, in which case releases must occur before any acquires will be granted.
