Subject: [PATCH] doc: additional disclaimers
Date: Thu, 12 Jan 2017 22:45:38 +0000	[thread overview]
Message-ID: <20170112224538.18771-1-e@80x24.org> (raw)

Honestly, these disclaimers should've been there all along;
and should apply to all servers handling multiple clients
within a single process.

+Rainbows! is extremely sensitive to fatal bugs in the apps it hosts.
+Each Rainbows! worker process may be handling thousands of clients;

+Rainbows! hackers are not responsible for your application/library bugs.
+Use an application server which is tolerant of buggy applications
