As I understand it, we should be fairly safe in this respect, because
the soname change reflects an ABI change that *already* happened
between 3.5.7 and 3.6.1, so anything in sarge/sid that's linked
against libtiff.so.3 is effectively getting libtiff.so.4 anyway.
There might be issues with global/static variables if the dynamic
linker satisfies some references from the instance labeled "3" and
some from the instance labeled "4", but I think they would only affect
programs that dlopen libtiff-using libraries without RTLD_GLOBAL.
Anything built against 3.5.7 (such as leftovers from woody) that pulls
in a library that's been rebuilt against 4.0 is also going to be in
trouble, but there's no way we can prevent that.
