[PATCH] Add current-suspendable-io-status parameter

Hi folks!
Here's a patch to add current-suspendable-io-status:
Its result is a pair: (finished-bytes . rest-bytes)

This is useful for designing a proper scheduler algorithm for
suspendable I/O operations.
For example, the server-core based on delimited-continuation can
compute a priority based on this status to decide how to schedule the
suspended task.

Comments are welcome.

Best regards.
