bugfix: lib/sh/util.sh: convention of fds to use for command-specific alternate stdin/stdout/stderr: changed to 40/41/42 because 10/11/12 are used by eval (which is used by set_fds()). use of fd 10/11/12 will cause hard-to-find silent bugs because exec will not print an error when these are used. documented why not to use other series of fds for this purpose:
