RAMDirectory(Directory dir, boolean closeDir) constructor uses memory
inefficiently.

Key: LUCENE-475
URL: http://issues.apache.org/jira/browse/LUCENE-475
Project: Lucene - Java
Type: Improvement
Components: Store
Reporter: Volodymyr Bychkoviak
recently I found that RAMDirectory(Directory dir, boolean closeDir)
constructor uses memory inefficiently.
files from source index are read entirely intro memory as single byte array
which is after all is thrown away. And if I want to load my 200M optimized,
compound format index to memory for faster search I should give JVM at least
400Mb memory limit. For larger indexes this can be an issue.
I've attached patch how to solve this problem.
