Just thought I'd have a go at it myself, using regex instead of the (obviously better) XOR approach.
My rough check, with 1 mismatch, works out to the same order of magnitude as choroba's first try, but maybe 2x slower. With more mismatches, my solution goes exponential creating regexes, but should take a bit less time in the matching phase. (Hand-wavy arguments go here.)
