Sorry for not having been able to participate in this discussion more 
attentively: On MacOSX this temporary fix doesn't work, there is no 
'timeout' command. I haven't seen any equivalent command either.

However, I found something, starting from Michèle's observation that 
some ps files are not blocking. What I found sounds crazy, but I have 
tested it.

If one replaces the first line in the ps file, something like

%!PS-Adobe-2.0 EPSF-2.0

just before the file is processed by ghostscript, by

%!PS-Adobe-3.0

then it works! Note the version and the absence of EPSF.

Since this claim is a bit outrageous and I don't have an explanation 
(except that I suspect the somewhat simplistic function 
encapsulate_postscript()), I hope that others can confirm.

For the Fink package, I made version 1.0.1.13-1 with the following 
patch. Please test.
