I ran into similar issues when I developed Chef::ShellOut, which I found were 
caused by object allocation during GC. Since I did not have the option of 
forcing people to upgrade to a ruby without the issue, I disabled GC for the 
affected portion of the code. You could try replacing popen4 with shell_out 
and see if this fixes the issue.
