Thank you for the information and the attention. What occurred to me may
be desirable to make the code less fragile and easier to debug may be to
'flatten' out the asynchronous operations so that the handler-queue for
any async process only has one item. Possibly this can be done by
passing the handler object as is done now, but using it only as a
boolean test to see if the operation is currently running async, and
only if not to create an async at that point.

In the meantime, I do seem to have fixed the bug that I discussed in
message [12926] (2018-02-23); however, there are a number of other
things that will show in a simple patch, so to isolate it for submission
may be some more work. For instance, I converted the code in w3m.el to
be lexically-bound throughout). Also, in the course of the work, I found
that the code was not following the promised documentation in how it
deals with the data structures `w3m-content-type-alist' and
`w3m-doc-view-content-types', and my current state of code seems to fix
those issues as well.

If there is interest in my current working version of the code, it would
probably be best to post it in entirety instead of as a patch; I can do
that offlist for anyone who asks, or onlist if that is appropriate.
