To my knowledge gdb can be used to inspect core dumps but not to
run anything (set breakpoints, singlestep, etc.) in 1.0. That
really sets some limitations to 1.0 usage (for me at least).

Are there separeate 64-bit system calls in the system call table
so that old 0.9 32-bit binaries don't confuze the kernel?
