Subject: Get rid of E_SIGNAL_PIPE.
X-Git-Tag: v0.3.0~284
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=dcf9594fa041cdfae819186ed7e145d079110318

Get rid of E_SIGNAL_PIPE.

If creation of the signal pipe fails, we abort anyway. So print
the errno in the fatal log message instead of the fact that the create
failed.
