While linking in gnu readline has the appeal of a well known and very
useful feature set, I can think of some disadvantages:

1. C code, requiring interfacing with erts code.

2. Risk of segfaults from code maintained by outsiders. There go the 9
   9's of uptime.

3. Various version control/config management headaches.


Probably better for one of us outsiders with lots of free time to
contribute readline.erl. I should be able to get to it by 2008 or
so. :)
