You *really* want to take the time to re-write the software to do things The Linux Way. If you're looking at doing on-the-fly patching, you're probably also carrying around a lot of *other* ugly cruft to make this creeping horror work on Linux. In fact, I'd not be surprised if you have a shim layer to make the compatibility layer for the *previous* system work on Linux... I'm reminded of a (possibly apocryphal) quote from an ATT spokesperson from 1988 or so, when a misplaced comma in a patch kept crashing the long-distance phone network. When asked "Why don't you just reboot the affected switches?" his response was "This assumes that the switch had ever been booted in the first place". (Apparently, the *whole thing* had been on-the-fly replaced/patched without an actual reload happening...)
