On Linux you can look somewhere in /proc, but I don't know that it

"/dev/fd" is actually a somewhat portable way of getting this
information. I don't think it's part of a standard, but on Linux it's
usually a symlink to "/proc/self/fd", and it's available on MacOS and
most BSDs (based on a hasty and completely-not-comprehensive
investigation). But it won't help you find out when the FDs were
originally opened, no.

On OS X and Solaris, dtrace and ustack will tell you exactly when and
where the FDs were originally opened, though. On Linux, SystemTap might
give you the same information (but I know much less about SystemTap).
If http://bugs.python.org/issue4111 is resolved, then this may even be
possible without using a patched version of Python.
