|
||||
* needle only prints once it has verified, byte for byte, the exact
|
||||
* payload pipesrc.c wrote through the real pipe) -- this thread's only job
|

* redirwriter/redirreader's own trivial one-shot work (a single write or
|
||||
* read-to-EOF, neither ever sleeps or blocks on a timer) needs to spawn,
