Description of problem:
there is bug in 2012-01-01+ ksh hangs when application does some dark magic with file descriptors


How reproducible:
always

Steps to Reproduce:
(set some nice memory ulimit, it eats memory quite fast)
ksh -c 'latestver() { rpmdev-vercmp 1 2 >/dev/null; } ; echo $(latestver)'
  
Actual results:
hangs


Expected results:
pass (no output)

Additional info:
rpm* python scripts do something weird with file descriptors, but ksh still should not hang. I was not able to reproduce this with anything different than rpm* python things.
