Just a remender: that that will only affect Python code running in the
current VM.  It doesn't actually change the Unix "stderr" file
descriptor (file number 2) that _might_ still be used by some external
libraries to print error messages, and it won't affect any child
processes (even Python apps).  You can deal with those cases by
replacing the standard error file descriptor with a log handler, but
it's a bit fiddly -- so I won't bother you with the details unless it
turns out you really need to do that.
