hog: n.,vt. 1. Favored term to describe programs or hardware that seem to eat
far more than their share of a system's resources, esp. those which
noticeably degrade interactive response. Not used of
programs that are simply extremely large or complex or that are merely
painfully slow themselves. More often than not encountered in qualified
forms, e.g., memory hog, core hog, hog the
processor, hog the disk.
“A controller that never gives up the I/O bus gets killed after the
bus-hog timer expires.”
2. Also said of people who use more than their
fair share of resources (particularly disk, where it seems that 10% of the
people use 90% of the disk, no matter how big the disk is or how many
people use it). Of course, once disk hogs fill up one filesystem, they
typically find some other new one to infect, claiming to the sysadmin that
they have an important new project to complete.
