* The space command forces an immediate update. Sometimes, on loaded
* systems, this update will take a significant period of time (because all
* the output is buffered). So, if the short-term load average is above
* "LoadMax", then top will put the cursor home immediately after the space
* is pressed before the next update is attempted. This serves as a visual
* acknowledgement of the command. On Suns, "LoadMax" will get multiplied by
* "FSCALE" before being compared to avenrun[0]. Therefore, "LoadMax"
* should always be specified as a floating point number.

* work best if the number is a prime number that is about twice the number
* of lines in /etc/passwd.

* to a file). Note that Nominal_TOPN is a default: it can still be
* overridden on the command line, even with the value "infinity".

* then getpwnam is used and the result is cached. If not, then getpwent
* is used to read and cache the password entries sequentially until the
* desired one is found.

* Configure script. Then if its value is 0, we undef it.
