A fast outputting program can halt the gvim with conque

[GoogleCodeExporter]

I wrote a program which has a busy output.
I run it in the shell open by conque in gvim
Then the whole gvim lost response, until I kill -9 the program.
htop shows that the gvim was taking 100% of the CPU, however, 
the program itself is not taking much CPU.

I've seen this happen a few times before, I think when greping a bunch of one 
line, many thousand character files.

I'll take a look.

A fix has been checked into trunk, and will go out with the next release. If 
you want it before then, make the following changes in 
.vim/autoload/conque_term/conque_subprocess.py
