Non-blocking wait was brought up. I think we can add it. It would be
non-blocking wait on specific processes though, I think doing a wait for
*any* process is a more difficult problem to solve, and is not supported
in the current std.process. It may be something added later.
2, What about nonblocking read/writes or support for timing out
reads/writes at least. On linux you can select() on the file descriptor
but that is not supported on windows.
This is not an issue with std.process, but rather with File. If File
doesn't support non-blocking read/write, that is an issue, but we should
solve it for all streams, not just pipes.
I believe that support for nonblocking operation is important since
spawning external processes is a common way to parallelize work and
std.concurrency could take advantage of this as well.
I agree, and would love to see File support non-blocking operations.
