I'm not sure how you're counting, but many POSIXish systems use gmalloc. These include FreeBSD, NetBSD, OpenBSD, HP-UX, AIX, and IRIX. Of course it's possible that there are memory allocation glitches on such systems, glitches that we haven't caught in the four years we've been using SYNC_INPUT. But any such glitches would be an independent bug, i.e., a bug that we should fix independently of whether we remove --without-sync-input. And the glitches can't be that serious, or we'd have noticed them before now.
