One more tidbit.  I re-installed your patch and deleted
linuxpluginwrapper and linux-flashplugin6.  The above
patch works fine.  Of course, any web page that use flash 6
becomes somewhat useless.

I also rebuilt libpthread with debugging option -g.  The 
trace shows

(gdb) bt
#0  0x48a77a2b in kse_thr_interrupt () at kse_thr_interrupt.S:2
#1  0x48a65d1e in sig_daemon (arg=0x0)
    at /usr/src/lib/libpthread/thread/thr_sig.c:214
#2  0x48a6fae7 in kse_sched_single (kmbx=0x17f)
    at /usr/src/lib/libpthread/thread/thr_kern.c:880
#3  0x00000000 in ?? ()
Current language:  auto; currently asm
(gdb) quit

This doesn't make any sense to me, so maybe gdb is having
trouble tracing the core dump.
