That is true for most libraries. In fact, if you want to do that, you need to get an explicit assurance from the library that it is supported. Qt offers no assurance, so don't assume that it works. I've wanted for some time to add a function that initialises the subsystems that can survive a fork-but-no-exec, like loading all of the plugins. I've never got around to to doing it. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
