Greetings! I do
M-x TeX-documentation-texdoc and supply the argument amsmath when prompted. An evince window fires with the documentation but emacs is blocked until I exit evince. If I try the same thing with tex-doc, evince fires but emacs remains usable. Experiment suggests that the former uses shell-command-to-string and this blocks while the latter uses call-process to fire texdoc and this does not block (or, at least, exits once texdoc has handed off to evince).
