I have no objection to apply the regex-25-percent-speedup.patch.
However, Could I have a rather longer period of grace to apply the other
patches?

Since I'm now working on fixing the bad algorithm which causes the bad
performance, and the fix might be going to spoil your optimizations
based on cache profiling.

I'm so sorry that I haven't prepared the fix yet, I'm swamped with my
side (regular?) business.

Thanks,
