--- Comment #37 from Sergey Matveev <earthdok at google dot com> --- I've patched LSan to use the real memset(). At least on my machine this brought no performance improvement compared to kcc's latest change (just FYI - not trying to make any point). As of now, LSan will still clear out the entire small chunk (which can be up to 128KB in size), compared to a default of just the first 4KB in ASan. I'm undecided as to whether this is worth changing.
