Subject: in select: interrupt

Anyone getting errors like this.... I'm working on a console mode full
screen editor (that Dossy kindly prototyped for me years ago).
Basically, it's reading $STD_IN with a select, thusly:


        if select([@in_io], nil, nil, 1)
        c = @in_io.sysread(1)


{lots of stuff to process the input follows...}

Funny thing is, there seems to be a finite amount of code that can be
below here, in the input loop.  After I add a certian amount, I start
getting funny errors while I'm typing in the editor, either in select:
interrupt, or the program simply says "Quit" and abends.

If I take some code out, the behaviour stops.  Problem is, I need this
code.  I was also having the same issues when i was using
term/ansicolor.  I wrote my own ansi module and this went away, until
I started adding code to the select loop.
...
I've used select in this way before, on a TCP/IP socket, with no issues....
