1. Favoured term to describe programs or hardware that seem to
eat far more than their share of a system's resources,
especially those which noticeably degrade interactive
response. *Not* used of programs that are simply extremely
large or complex or that are merely painfully slow themselves
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 file system, they typically find some other new one to
infect, claiming to the sysadmin that they have an important
new project to complete.
