CVS commit: src/sys/kern

[Darren Reed <darrenr%netbsd.org@localhost>]

Module Name:    src
Committed By:   darrenr
Date:           Thu Mar  6 15:31:15 UTC 2003

Modified Files:
        src/sys/kern: kern_sig.c

Log Message:
When unblocking threads, do not call setrunnable() on the thread we will
be returning because the code path that calls is will very likely call
setrunnable() again on the returned thread, leading to a panic because
the thread returned is already at LSRUN.  This fixes a problem where netbsd
would panic when using gdb (5.3) on a process with multiple lwp's like this:
% gdb program
(gdb) run
^C
(gdb) quit
