So my question is: is this code thread safe, wrt to other Zope threads accessing the os module methods while they are redirected to mine ? I don't want other Zope threads to access my own methods, just the current one.
The cheeky solution involves using the standard library module rexec. It was designed for replacing modules in a security sandbox (for example, replacing the standard 'open' function with one that limits access to a specific directory) but it will do exactly what you want too.
The python documentation for this module is a little thin, but there is deeper documentation on www.python.org.
I really don't understand how to do that, does someone have working examples ? thanks in advance ! Jerome Alet
