I'm curious, shouldn't GC be automatically called when heap near limit

It definitely should.  However, calling it manually is harmless except for wasting CPU time.

Calling first (GC :full t) and then (ROOM) is a test to find out if you have generated uncollectable garbage, that is objects you don't need but still have a reference to somewhere.
