When I posted the above, I hadn't yet applied the patch
mentioned in the wiki page.  When I did, valgrind itself
crapped out:

==18736== Warning: client switching stacks?  SP change: 0xBE857B4C --> 0x48DFFF0
==18736==          to suppress, use: --max-stackframe=1174963364 or greater
--18707-- INTERNAL ERROR: Valgrind received a signal 11 (SIGSEGV) - exiting
--18707-- si_code=1;  Faulting address: 0x57E58959;  sp: 0x62527DA4

valgrind: the 'impossible' happened:
   Killed by fatal signal
==18707==    at 0xB001AB5C: vgPlain_get_StackTrace2 (m_stacktrace.c:147)

==18707==    by 0xB003BC5D: run_a_thread_NORETURN (syswrap-linux.c:119)

so I guess there's definitely some work left to do on valgrind...
