Yep, that looks like the Emulation Technolgy zif socket (or at least
that's what I call it). Never heard the term "coffin" but it seems
appropriate for a couple of reasons.

I guess it depends on how well you install it, but I had one of these
lift the traces on a board I was working on, after a few dozen cycles of
in and out. Almost put me in a "coffin" since I was debugging a program
where the bug turned out to be an intermittent on the socket. So I
would be very gentle with it. I never tried it, but epoxying it to the
PCB might make it more rugged.
TSOPs are neat for their size, but they sure are delicate for R&D use.
I have found them to be tempermental on my EMP programmer as well.
I don't know of a better solution, BTW, just an FYI.
