If we're limited to Linux kernels, this seems to not be the case. Great care is taken in keeping this userspace ABI stable -- new system calls are given new numbers. Old system calls may disappear (after a long grace period) but even then I don't believe the number is ever recycled. If your discussion is not limited to Linux kernels, then sure, but being portable at that (sub-libc) level is asking too much. > I hope that I made some sense. Some, but your supposition seems unclear.
