This is a breaking change, but it is time to rip the bandaid off. `syscall.Dup2()` will never be merged upstream[1]. Software depending on `syscall.Dup2()` needs to move to use `unix.Dup2()`.

…syscall` package.
On Illumos `mmap(2)` can return `EAGAIN` when a process is running low on available RSS. At best, not trapping `EAGAIN` leads to misleading error messages.

The updated go-1.8.1nb2 package just landed in 2016Q4, though the mirrors might take an hour or so to synchronize. |
