Modified Files: src/bin/sh: main.c Log Message: If we are invoked with SIGCHLD ignored, we fail badly, as we assume that we can always wait(2) for our children, and an ignored SIGCHLD prevents that. Recent versions of bash can be convinced (due to a bug most likely) to invoke us that way. Always return SIGCHLD to SIG_DFL during init - we already prevent scripts from fiddling it. All ash derived shells apparently have this problem (observed by Martijn Dekker, and notified on the bash-bug list). Actual issue diagnosed by Harald van Dijk (same list).
