{AJ} The GNU C library uses thread safe functions by default and libc5 used
non thread safe versions. The non thread safe functions have in glibc the
suffix `_unlocked', for details check <stdio.h>. Using `putc_unlocked' etc.
instead of `putc' should give nearly the same speed with bonnie (bonnie is a
benchmark program for measuring disk access).
