Good observation. I usually look at the build log and file bug reports
when I see that happen. It can take a while to learn to recognize, but
it usually takes less than a minute to spot. I could probably automate
it with a shell script and grep. Hm.

(Parallel building cuts my build time for a full system two a mere few
hours, IIRC. A serial build of a full system takes could be started
before I go to sleep, and wouldn't be done before I went into work the
next day.)

(I tried tricking genlop into giving me the build time of an emerge
-pe by putting -e in EMERGE_DEFAULT_OPTS, but it appears to be hung.
:( )
