Subject: [PATCH 1/2] Add a note about timeouts on gen_tcp:connect/3,4

 The optional <c><anno>Timeout</anno></c> parameter specifies a
 time-out in milliseconds. Defaults to <c>infinity</c>.

+ Keep in mind that if the underlying OS <c>connect()</c> call returns
+ with a timeout, <c>gen_tcp:connect</c> will also return with a timeout

 The default values for options specified to <c>connect</c> can
 be affected by the Kernel configuration parameter
