The real problem here is that some people don't want Python to write
any .pyc files, period. So even if mailman byte-compiles all its
source code, it can't stop Python from writing .pyc files that belong
to mailman. That, in turn, can cause the problems discussed in this
thread: there might be races in doing so, it might trigger security
alarms, and it might write byte code files in configuration areas of
the system where only text files are allowed, per policy.
