Simultaneous with the conversion to scala 2.10, memory behavior is much worse.

When I run unit tests now, it fails due to out of heap, or GC overhead limit exceeded. This is true even when the JVM is given 6Gig heap space.

One test, test_ExplicitLengthBytesNotGiven, allocates a giant array.

This test fails now, and its presence in the suite really aggravates things. It is commented out now because it makes forward progress working impossible.

Without that test, behavior is still bad. Tests run, but are broken up by GC pauses which happen more and more frequently as tests are run (from sbt).

So something is leaking memory now.
