(This is true even in single-threaded | code, in fact.) Hmm - yes, that's non-trivial to fix as there's no tm_free() function. Probably we'd need to simply retain all of the tzabbr lists, rather than including them directly in the state struct), for all zones ever loaded (just once, so we don't burn memory when returning to a zone for the second time) and suffer the cost of that - which isn't much, as the string size is small (typically < 20 bytes/zone, usually much less) and the number of zones is bounded, the number actually used by an application likely much smaller, so the total cost is going to be small. kre
