CompiledExecutables defines a set of executable objects that are precompiled and the compilation stored either in the ZODB or in the file system. It currently defines CompiledPageTemplate, FSCompiledPageTemplate and FSCompiledPythonScript (PythonScript is already compiled; although in a somewhat stupid manner (in __setstate__ rather than when used)). Storing the compilation result avoids expensive recompilation. This can drastically speed up access to the first pages after startup -- especially for large CMF based sites. The product does not register anything. It is up to you to register the filesystem based objects with Products.CMFCore.DirectoryView.registerFileExtension or the ZODB based objects by calling their initialize function. The product works by making instance methods and code objects picklable. This might appear as a security risk. However, unpickling untrusted pickles is always a security risk (because the pickler decides what is picklable and not the unpickler).
