[Webkit-unassigned] [Bug 163375] We should consider allocating a CodeBlock's Instruction stream away from other things

--- Comment #1 from Filip Pizlo <fpizlo at apple.com> ---
I wonder if we could add API to bmalloc to do this.  It would force those objects to be allocated from their own size classes.  If they get large, they would be allocated with guard pages around them, automatically.

Something like:

Foo* createFoo()
{
    static SeparateMallocSpace mySpace;
    return static_cast<Foo*>(fastMallocSeparate(mySpace, sizeof(Foo)));
}
