It appears to be a bash bug, with not setting close on exec on the fd it uses for its tty, in order to hide from shell scripts. The problem is that if you redirect input, bash has no tty on which to do reads, etc.. Feel lucky: it used to be worse. It uses to go out and try to get the highest posible fd for doing this crap, which meant waiting for it to eat up all of kernel memory chasing fd's until there was no more memory available for the per process open file table. All in all, bash is pretty buggy. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
