This allows me to replace libc_r.so* with libthread_xu.so* and use firefox (basic testing).  thunderbird sets scheduling parameters which do not match the ones supported by libthread_xu, so there is a little bit work left.
I believe that with a recompile threaded applications should work with
MALLOC_OPTIONS="G" now.
