Clearing the direction flag before calling a signal handler

[Peter Schuller]

Hello,

I found an exchange concerning a difficult to debug problem that may be 
affecting FreeBSD. I wasn't sure whether to post here or just file a bug, but 
under the circumstances I opted for the former. Apologies if it is considered 
noise.

I was reading the exchange here:

   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=469058

Referencing the following patch to Linux;

   http://lkml.org/lkml/2008/3/5/306

The exchange in the Debian bug tracker indicates kfreebsd 6/7 has the same 
problem as Linux. Being a kernel issue, that indicates vanilla FreeBSD may 
likely be affected.

I neither have the setup nor the knowledge to effectively evaluate this 
myself, but felt that it was obscure/diagnostically difficult enough that i 
wanted to bring it to somebody's attention.
