FileHandle gets a hasDataAvailableForRead() getter. If this returns true in sys$read(), the task will block(BlockedRead) + yield. The fd blocked on is stored in Task::m_fdBlockedOnRead. The scheduler then looks at the state of that fd during the unblock phase. This makes "sh" restful. :^) There's still some problem with the kernel not surviving the colonel task getting scheduled. I need to figure that out and fix it.
