The last time I looked at the Apache source code, it didn't use very
much shared memory, at least on Unix and similar systems. It operates
on a scheme of multiple independent processes with their own memory
space. Shared memory is used only for the "scoreboard", which keeps
track of the various processes and their state.
The shared-mem portions of the code were also the most complicated, at
least from a preprocessor point of view. There were at the time about
eight different implementations, one of which would be selected based on
what was available on the target platform. So the answer to your
question is "yes", it uses those types of shared memory, but to get a
more-specific answer you need to look at the source code. Or at least
try running "nm" against a compiled copy to see what's there.
