Hi, I cannot reproduce the problem (using my quite recent GODI installation). That EINPROGRESS "breaks out" is quite strange, because the HTTP connection is made via Uq_engines.direct_connector, and there it is caught. A subtle problem I could imagine is that one of the libraries includes unix.cma erroneously (i.e. the Unix module is defined twice), and because of this there are two versions of Unix_error, and one cannot catch this exception anymore. You could check this by running ocamlobjinfo on the cma files, and looking whether a "Unit name" of Unix occurs (should only be in unix.cma). (Btw: Do you see the problem also for ocamlopt-compiled programs? cmxa's cannot be partially linked, unlike cma's, so a linking problem is not possible.)
