Subject: Lock the tables as low-priority when writing.  Maybe makes people making changes... 
X-Git-Tag: bugzilla-2.12~386
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3c0ea11d42d7942f36e1704afefc55655811db5d;p=thirdparty%2Fbugzilla.git

Lock the tables as low-priority when writing.  Maybe makes people making changes wait longer, but people doing read-only stuff should now never block for very long.
