Andreas Kling	c6f2890d8e	Implement a basic way for read() to block. ... 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.	2018-10-25 13:09:56 +02:00

Andreas Kling	1f41a36c52	Add a Unix namespace for foo_t types. ... This allows me to keep prototyping things on a random desktop machine, even if that machine has its own ideas about foo_t types.	2018-10-14 22:57:57 +02:00
