No, I ignored them.  But to create a so-called "suppressions" file,
you can invoke valgrind with --gen-suppressions=all.  You select
the ssl-related entries and put them in a file, say F, then whenever
you run valgrind, use --suppressions=F to make it ignore those.

BTW, Here are a few more that I haven't investigated:

Then, just for grins, I ran chunkd (via make check)
under valgrind with --gen-suppressions=all, which generated 27000
lines of suppressions, and extracted the unique ones.
Even those could be further consolidated with frame-level "..."
wildcards (see http://valgrind.org/docs/manual/manual-core.html)
but that would take careful manual work.

Here's the result.  Obviously, before using these, you'll want
to ensure that each really does represent an ignorable condition.
For the ssl-related signatures, it's pretty easy to assume.
For most of the others, it'll require careful work.
