Add constructor to create RAF with fixed length.
Test: Factory method can throw.
IllegalArgumentException if negative offset.
Tests for RandomAccessFileWrapper.
IllegalArgumentException here too.
Fix test-breaking bugs in pooled...
Allow changing the size of the pool and querying how many fd's are open.
Javadocs.
Fix memory leak: Remove from closables list when closing! Oops.
Basic tests for PooledRAF (no pooling yet, just check basic functionality).
Test that pooling works - can write to two files with a fd limit of 1.
Package-local status counts for tests/stats.
Test locking.
Lock on closables queue, not class. Thanks bertm for suggestion.
