The problem is that Linux applications using old Linux threads (pre-NPTL) use signal 32 (linux SIGRTMIN) for communication between thread-processes. If such an linux application is installed suid or sgid and security.bsd.conservative_signals=1 (default), then permission will be denied to send such a signal and the application will freeze. I believe the same will be true for native applications that use libthr, since libthr uses SIGTHR for implementing conditional variables.
