When block storage tests are enabled, test runner JVM runs out of heap

[GoogleCodeExporter]

This seems to indicate inproper resource cleanup from the byte buffer block 
storage option.

Essentially after a few test runs with a cache storage of 32m, the JVM runs 
out of heap.

Seems to be a memory leak; starts to occur after multiple daemon creations in 
the same 
test runs (multiple configurations)

Problem is localized to the ByteBufferBlockStore but not the memory-mapped 
version of 
it. Likely related to the cleanup of the byte buffer.

decreased total heap usage in tests, allocate buffer direct, and make sure 
resources 
are cleaned up more elegantly on shutdown. Likely need to spend more time with 
a 
profiler here verifying proper cleanup, but this particular bug is closed for 
now
