Subject: bug#28149: 26.0.50; Emacs regularly hangs for multiple seconds in e.g. find-file

Hi Eli,
I tried and after bisection after bisection, hangs got less but did not
disappear. Then I did one final test with emacs -Q again and actually
managed, after several minutes, a hanging as well, after find-file with
completion in buffers with lots of files in it (/usr/share/... or
similar).
I come to the conclusion, that it probably is not an emacs problem at
all but rather a hardware or OS problem that manifests only in a singe
threaded application like emacs.
... the search continues ...
