Yes, that might also work.

Ah, that makes sense, thanks.  I guess we could also use creatively
wildcarded strings like *boost*detail*get_once_per_thread_epoch*?

That has demangled symbol names in it.  They should be non-demangled,
and that's why it doesn't match.  The easiest way to get the non-demangled
names is to run with --gen-suppressions=all and copy what you get from
there.  Or you can play games trying to correlate the output of "nm" and
"nm | c++filt" for the binary, and try to figure out the names from that.

You can see mangled names in other parts of the same file, for example at
https://github.com/ceph/teuthology/blob/master/teuthology/task/valgrind.supp#L142
