Description
The attached code will demonstrate this problem.
It simply:

1. Gets a list of all Source Lines supported by a given system.
2. Cycles through the list of lines opening then closing each in turn.

Eventually an invocation of the "close" method, will cause the system will hang.

This problem has been witnessed on all platforms.
This problem is a block to reliability testing.
