Subject: [PATCH] Revert "Handling collision between standard i/o file
descriptors and newly created ones"
g_unix_open_pipe tries to avoid the standard io fd range
when getting pipe fds. This turns out to be a bad idea because
certain buggy programs rely on it using that range.
This reverts commit d9ba6150909818beb05573f54f26232063492c5b
Closes: #2795
Reopens: #16
Conflict:NA
