bug 3192 - write to process on OS X

[Bernard Devlin]

Hi folks,

As Monday is the deadline for people contacting Bill with votes for  
outstanding bugs, I'd just like to say that if anyone has votes left,  
then this one is a good candidate.

There are times when the shell() function is simply not adequate in  
interacting with command-line programs.  Some of these programs e.g.  
the various isql shells, are interactive, so they need 'write to  
process' and 'read from process'.  The Rev docs just tell us to use  
shell() on OS X, but that is simply not enough. There is simply no  
workaround for this particular bug, so I feel it really should be fixed.

These features work on Windows, but not on OS X.  Here we have a unix  
with tons of command line programs that we can write lush GUIs for,  
except we can't have this kind of interaction on OS X without this  
bug being squashed.
