English: I suspect that the problem is that safe_mysqld don't return 
until mysqld ends.
Try to execute safe_mysqld in background in the shellscript:

	if ! pgrep mysqld
	then
		/usr/bin/safe_mysqld &
	fi	
	
Castellano: El problema debe ser que no termina safe_mydqld hasta que no 
termina mysqld. Se podría solucionar llamando a safe_mysqld en 
"background" de la forma anterior.
