** I would say "unaffected" except that our use of <code>JS_malloc()</code> might end up decreasing so much as to defeat the purpose of this. So maybe we need a new heuristic for <code>JS_MaybeGC()</code>. The only other place gcMallocBytes is directly used is for jsscope.c for changing scope (it allocates space with calloc but treats it as a malloc). Ask Brendan. | ** I would say "unaffected" except that our use of <code>JS_malloc()</code> might end up decreasing so much as to defeat the purpose of this.

** I'm expecting to use MMgc, rather than <code>JS_malloc</code>, to allocate the character buffers for strings. (This is what Tamarin does. Otherwise, <code>JSString</code> would have to have a finalizer.) -jto | |||
