Subj : Puzzling assertion in js_AllocGCThing()

I'm working on tracking down failures in Sablotron (open source XSL/T
engine) when JavaScript is used, and I've run into an assertion in jsgc.c
(line 461) from SpiderMonkey version 1.5 RC6:

  JS_ASSERT(!rt->gcRunning);

Could someone explain why the assumption that no other thread would be
running garbage collection when js_AllocGCThing() is invoked is valid?  If
there is a good explanation for this assumption, I'll take it back to the
maintenance team for Sablotron, and there's a good chance that we'll have a
good clue for the underlying cause of the failures we're seeing.

Thanks very much!
