Comment (by was):
I think this code is too slow. We want it to be highly optimized so as to
not have much of a performance penalty for introducing a stopgap. I'm
going to attach a different patch that implements stopgaps, and is an
*order of magnitude* faster than this code:
{{{
sage: timeit("sage.misc.misc.stopgap('abc', 123)", number=10^5)
100000 loops, best of 3: 2.49 µs per loop
sage: import sage.misc.stopgap
sage: timeit("sage.misc.stopgap.stopgap('abc', 123)", number=10^5)
100000 loops, best of 3: 388 ns per loop
sage: 2.49 / .388
6.41752577319588
}}}
