Unhandled EPIPE Exception in _fcgi.py

[anonymous]

When running trac with fcgi and lighttpd, I observe following messages: It seems that EPIPE is not handled properly.

    File "/usr/lib/python2.4/site-packages/trac/web/_fcgi.py", line 654, in run
        self.process_input()
    File "/usr/lib/python2.4/site-packages/trac/web/_fcgi.py", line 690, in process_input
        self._do_params(rec)
    File "/usr/lib/python2.4/site-packages/trac/web/_fcgi.py", line 789, in _do_params
        self._start_request(req)
    File "/usr/lib/python2.4/site-packages/trac/web/_fcgi.py", line 773, in _start_request
        req.run()

This patch may fix this, please review

I wrote the patch after reading: ​http://www.fastcgi.com/docs/faq.html#Signals

I guess this is how to fix it, but I am not really sure, whether the exception should be handled in a different way.

I'm fixing the description formatting. The {{{ and }}} should be on a separate line for pre-formatted blocks.

[Matthew Good]

Hrm, there is a place in _fcgi.py that should be catching the EPIPE exception already, so I'm not quite sure why it's not getting caught there. I'll try to take another look at this.
