It sounds more like the sort of issue that would be *created* when
threading was implemented.

Based on what Stefan said, a more helpful question might be: what
happens between the call to match-string and the call to
replace-match?  Are they in the same function, and close together?
What can match-string tell you about the string you're trying to
replace?
