- * other possible implementation using intel builtin rdtsc
- * rdtsc-workaround: http://www.mcs.anl.gov/~kazutomo/rdtsc.html
- *
- * we could get the ticks by doing this
- *
- * __asm __volatile("mov %%ebx, %%esi\n\t"
- * "cpuid\n\t"
- * "xchg %%esi, %%ebx\n\t"
- * "rdtsc"
- * : "=a" (a),
- * "=d" (d)
- * );
-
- * we could even replace our tricky sched_yield call by assembly code to get a better accurency,
- * anyway the following C stub will satisfy 99% of apps using posix clock_gettime call,
- * moreover, the setter version (clock_settime) could be easly written using mach primitives:
- * http://www.opensource.apple.com/source/xnu/xnu-${VERSION}/osfmk/man/ (clock_[set|get]_time)
