The attached patch triggerises the invocation of ldconfig by package
maintainer scripts.
By `triggerises' I mean that the patch arranges for ldconfig
invocations by maintainer scripts to call dpkg-trigger instead of
ldconfig. ldconfig

ttyname() should return the name of the tty device in a form than can
be used by other processes (with different controlling terminals) to
open it.
Steps to reproduce:
$ perl -e 'use POSIX; printf "%s\n", ttyname(STDIN)'
/dev/pts/117
$ perl -e 'use POSIX;

ill try to make a patch to fix ghostscript, or at least file a
proper bug. But, if there was a libc change, would it be possible to
revert it or make some kind of workaround ?

e. Whether to do that would depend on its performance impact.
TBH I wonder whether we really want to be giving an evidently shonky
codebase boobytrapped mutexes by default. We could change the default
mutex type to recursive and make all of these bugs go away.

Realistically our sensible choices for the default are

One of en_{AU,GB,NZ}.UTF-8
All of these would be better than en_US.UTF-8 for the reasons given
by Adam (although, Adam, really, could you try to be a little less
