>Description:
Top does a getpwent loop, which takes forever on NIS boxes with huge password databases.

I have a fix, but I'm filing this bug, so that my diff can be tested / checked in.  The -u option is supposed to avoid problems like this, but it was not being checked everywhere.
>How-To-Repeat:
top or top -u on a box with a big YP password file
>Fix:
Will submit diff when cvsup is finished building
