Subject: we are never interested in SIGPIPE so just ignore (block) it
X-Git-Tag: samba-2.0.0alpha3~22
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=72c383f4b7bcce5374632dc972df16ab0e2542b9;p=thirdparty%2Fsamba.git

we are never interested in SIGPIPE so just ignore (block) it
always. Don't even install a handler.
