What operating system and compiler?

That would do it across different architectures and particular changes
to the code (although then something should keep a record of what
pystone had been observed at what time). It won't do it across different
releases, because we don't have Python binaries for each release
available on each slave.

Unfortunately, there can't be a guarantee that the slaves are idle.
Several of them fulfill some primary function for whoever contributed
the slave installation (I know *my* Solaris machine has to do other
things, as well).
