pdf-tools, doc-view and emacs 27.1 in bullseye is very slow

[Boyan Penkov <boyan.penkov@gmail.com>]

Hello folks,

Just upgraded to bullseye, and pdf-tools and doc-view for the emacs
folks is very different:

-- startup is very slow, and emacs seems to stutter (like, pre-26,
pre-threading...) on conversion.

-- the place in the pdf is no longer reliably bookmarked

-- doc-view-fit-to-width is no longer reliable over restarts.

Anybody else seeing stuff like this?

Cheers!
