Re: [Chicken-users] readline blocks threads

[Elf]

the problem isnt nonblocking status.
the problem is that all the term settings get munged by readline - how else
could it interpret arrows, tabs, do paren bouncing, etc.
i am working on a pure scheme readlineish lib to compensate with approximately
the same feature set as what is presently there.  it should be done shortly.

however, instead of coding right now, im going through the almost 500 eggs
to make sure that the licence data is correct (ie, the licence tag and the
actual licence match and have the right names, and the docs match the
licences, and that all versioned licences have the proper version appended
to them (eg LGPL-2.1)) because the daily licence muddle has got to stop.
