I've just installed another patch for fontset.c in trunk.
With that, even in English language environment,
(insert-char #x2203 10000) is not that slow.

But, it may just hide the original problem of memory full.
I'll keep on finding why that happens.

It seems to avoid the problem in this case at least. I can now insert over a million of the characters from the original recipe without a problem (and within 5 seconds) by changing the 16 in the original recipe to 20.

I think this change should go in the release branch, then we can close the bug (or lower its priority if you would rather continue to investigate).
