I've no experience with Position-independent executables; A quick search 
does suggest that there's a performance hit (every time the program is 
loaded into memory ??).


For example:

From: http://www.redhat.com/magazine/009jul05/features/execshield/

   "Position independent code has a performance overhead on most
    architectures (x86-64 is the exception to this). For this reason,
    neither Red Hat® Enterprise Linux® nor Fedora™ Core have the entire
    distribution compiled as a PIE binary. Only selected, security
    sensitive programs are compiled as PIEs. "

Thoughts ??
