What is lacking from the current task.ijs ? This seems to be the
portable way to deal with tasks. The distinction between process and
task isn't clear to me
In this specific example:
fork_jtask_ 'sleep 10'
returns immediately by appending & (on linux)
fork_jtask_
[: 2!:1 '(' , ')&' ,~ ]
fork_jtask_ 'sleep 10'
('(' , ')&' ,~ ]) 'sleep 10'
(sleep 10)&
