Nothing is done here to prevent that, so be sure to not to configure the standard library logging module to block when used in conjunction with this module: code within Twisted, such as twisted.web, assumes that logging does not block. @cvar defaultStackDepth: This is the default number of frames that it takes to get from L{STDLibLogObserver} through the logging module, plus one; in other words, the number of frames if you were to call a L{STDLibLogObserver} directly. This is useful to use as an offset for the C{stackDepth} parameter to C{__init__}, to add frames for other publishers.
