To correct this.

This should be a reason why GDB runs slow on GNU/Linux, but, isn't!  Per 
other thread, this inefficiency (a few 1 000 stray ptrace calls() is 
trivialized by the millions (yes >1 000 000) memory read ptrace calls. 
GDB was probably executing more memory ptrace() calls than the target 
program executes instructions .... (yea, right :-).
