it's actually possible to run both 32-bit and 64-bit executables at the same time on a supported OS.
Solaris 10 does this, to the best of my knowledge (just use LD_LIBRARY_PATH and LD_LIBRARY_PATH32 appropriately). Ditto for AIX 5.3. Don't know about Linux or Windows 64-bit though.... I expect though that switching from a 32-bit to a 64-bit context is more expensive in terms of processor cycles.
