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.
