 After some consideration, I found that the code is running by mount which
forks every time.
 So the static flag is useless, AFAIK.

 The good news is: I took the time of that checking code and it is very
fast.
 On my 4x slower virtual machine, it took not more than 253 us.

 The code to take the time in nanosecond is attached to this email.
 If you think that it could be useful for busybox, take it.
