New issue 2703 by mari...@medikoo.com: Memory management issues observed in v3.19
http://code.google.com/p/v8/issues/detail?id=2703

I have a heavy configuration script that I run with Node. It's both memory and CPU intensive.

When run with Node v0.10. 8 (which is backed by V8 at v3.14.5.9) memory usage oscillates at 500-600GB and script finishes successfully. However when run with Node v0.11.2 (which is backed by V8 at v3.19.0) memory usage is more extensive, as it oscillates at 500-1GB and when reaching 1GB, script crashes with "process out of memory" error.

I've described it and provided a test case in https://github.com/joyent/node/issues/5590

Questions that come to my mind are:

1. Is it known and accepted fact that memory usage of V8 at v3.19 is more extensive than in v3.18 2. Is it ok that script crashes at 1GB memory usage if some of memory can be freed by garbage collector
