Another try. This patch is by far more efficient.
With the previous patch #1:

 % time grep -P faz /usr/bin/*                                            
 ...
 grep: /usr/bin/X11: Es un directorio
 grep -P faz /usr/bin/*  519,78s user 0,32s system 99% cpu 8:41,19 total

 With this one:

  % time src/grep -P faz /usr/bin/*
  src/grep -P faz /usr/bin/*  7,36s user 0,33s system 99% cpu 7,695 total

Cheers,
