Subject: Add extra sleep to avoid race condition
X-Git-Tag: 1.1.0~51
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=100f7dc950fa1fefad2d522826a794b6b9297916;p=thirdparty%2Frspamd.git

Add extra sleep to avoid race condition

When there are no expressions to compile it is possible that hs_helper
will send notice to no workers. So this sleep should resolve the most of
cases where this race occurs.
