It will check which scheduler it is running under and create the correct type of task as appropriate. Most options aren't supported but basic spawning works.
`switch_running_tasks_and_then` does a context switch to another task then immediatly runs a closure.

| // Make this a newtype so we can't do I/O on arbitrary integers | ||
| pub struct FileDesc(fd_t); |
There was a problem hiding this comment.
Probably this should be FileHandle as discussed yesterday, since on Windows it's HANDLE rather than a descriptor.

r? This pull request is a grab bag of work on the new scheduler. The most important commit here is where I [outline](https://github.com/brson/rust/blob/io/src/libcore/rt/io/mod.rs) a fairly complete I/O API, based on `Reader` and `Writer` types, as in the current `core::io` module. I've organized this version into a number of modules with declarations for Files, TCP, UDP, Unix sockets, blocking/non-blocking implementations, memory buffers, compression adapters. I'm trying to get this into shape to present on the mailing list. This branch also wires up `spawn` to the new scheduler, and simplifies the core scheduler operations.
