Bug#197828: apt: uses all of cpu waiting for disk

[Dan Jacobson <jidanni@jidanni.org>]

Package: apt
Version: 0.5.4
Severity: normal
File: /usr/bin/apt-get

When I used xargs, apt pegged my CPU meter to the max when waiting for
the disk

# xargs <i apt-get  install

# xargs <i 
icomlib-bin icomlib-doc icomlib1 icomlib1-dev pcrd qpcr1k


However without xargs, the CPU was peaceful

# set `cat i` 
# apt-get  install $@

OK, maybe I was blocking stdin or something, but still...
