Having looked at ruby/process.c and ruby/io.c in 1.9.3 and 2.0, I'd say the 2.0 behaviour is what always was intended, but it's very poorly documented. I believe (haven't verified) that you need to explicitly list the FDs that you want to pass on to the child in the exec options (see Process#spawn redirection); it appears :close_others changed meaning a bit to "any non-standard FD that's not in the redirection list" (from "any non-standard FD if enabled") and setting it to false no longer does anything. > P.S.: please keep the bug address in Cc:, thanks! -- ,''`.
