async I/O

[brnstnd at stealth.acf.nyu.edu]

I very much agree with Peter. The basic I/O calls should be asynchronous:
aread(), awrite(), and astatus(). aschedwait() and asyncwait() should wait
for scheduling and synchronization respectively; both should only be
special cases of a single await() call, with different semantics for
different devices and file types. Then my multitee program would be easy
to deal with, along with a host of related problems.

Exactly. read() and write() would be short library routines.

Yup, and select() is only half a solution. (select() and poll() would be
forms of the more logically named await().)
