- Process (a) is blocked in read on a socket waiting on data. - Process (b) is blocked in shutdown() on a socket waiting on (a). - Process (c) delivers a signal to (b) interrupting its wait. When the signal is delivered, the kernel panics as sblock() fails in sorflush(). Even if it didn't panic, shutdown() would block potentially indefinitely waiting for recv() to succeeded. Fixes to follow. Reported by: Jos Backus <jos at catnook dot com>
$FreeBSD$ This directory tree contains tools used for the maintenance and testing of FreeBSD. There is no toplevel Makefile structure since these tools are not meant to be built as part of the standard system, though there may be individual Makefiles in some of the subdirs. Please read the README files in the subdirs for further information.
