Mailing the story:

Syslets are a proposed mechanism which would allow any system call to be invoked in an asynchronous manner; this technique promises a more comprehensive and simpler asynchronous I/O mechanism and much more - once all of the pesky little details can be worked out. A while back, Zach Brown let it be known that he had taken over the ongoing development of the syslets patch set; things have been relatively quiet since then. But Zach has just returned with a new syslets patch which shows where this idea is going.
