For sqlite, at least, it uses Lwt_preemptive.detach and sqlite3 contains the required caml_enter/leave_blocking_section(s). So Lwt should work without problems with sqlite. I suppose it is the same for dbm. Regards, Sylvain Le Gall _______________________________________________ Caml-list mailing list.
