Keeping a lot of {state} in your head while modifying a program.
"Don't bother me now, I'm juggling eggs", means that an interrupt is
likely to result in the program's being scrambled. In the classic
1975 first-contact SF novel The Mote in God's Eye, by Larry Niven and
Jerry Pournelle, an alien describes a very difficult task by saying
"We juggle priceless eggs in variable gravity." It is possible that
this was intended as tribute to a less colorful use of the same image
in Robert Heinlein's influential 1961 novel Stranger in a Strange
Land. See also {hack mode} and {on the gripping hand}.
