Some folks appear to be using it, but I suspect it is not /widely/ used.
Then again, a possibly buggy session persistence mechanism is probably
better than the standard implementation that will definitely crash your
JVM after a while. :)

I don't believe you can control these settings. The documentation
doesn't even say that LRU is used.... it's all about idleness: if a
session is idle for a specified amount of time, it gets stored and
evicted from memory.
