+    <pinotree> youpi: hm, thought about the pthread/stubs issue w/ dlopen'ed
+      libraries
+    <pinotree> currently looks like libstdc++ on hurd links to pthread-stubs,
+      we're the only one with such configuration
+    <pinotree> i was looking at the gcc 4.4 patch hurd-pthread.diff, could it
+      be it does not set THREADLIBS in the configure.ac switch case?
+    <youpi> that's expected
+    <youpi> on linux the libc provides hooks itself, on hurd-i386 it's
+      pthread-stubs
+    <pinotree> why not explicitly link to pthread though?
+    <youpi> because there is no strict need to, for applications that don't
+      need libpthread
+    <youpi> the dlopen case is a tricky case that pthread-stubs had not thought
+      about
+    <pinotree> hm
+    <pinotree> what if the pthread stubs would be moved in our glibc?
+    <youpi> that's what we should do yes
+    <youpi> (ideally)
+    <youpi> but for this we need to build libpthread along glibc, to get it
+      really working
+
+[[Packaging_libpthread]].
+
+    <youpi> and that's the tricky part (Makefile & such) which hasn't been done
+      yet
+    <pinotree> why both (stubs + actual libpthread)?
+    <youpi> because you need the stubs to be able to call the actual libpthread
+    <youpi> as soon libpthread gets dlopened for instance
+    <youpi> +as
+    <pinotree> i see
+    <youpi> (remember that nptl does this if you want to see how)
+    <youpi> (it's the libc files in nptl/)
+    <youpi> (and forward.c)
+    <guillem> also if libpthreads gets integrated with glibc don't we need to
+      switch the hurd from cthreads then? Which has been the blocker all this
+      time AFAIR?
+    <youpi> we don't _need_ to
+    <guillem> ok

     <youpi> there's one known issue with pthreads
     <youpi> you can't dlopen() it
