bug#45544: 27.1.90; Slow org-capture on OpenBSD X

[Timo Myyrä]

Hi,

Emacs is by default very slow when running org-capture when using
graphical emacs on OpenBSD. This behaviour has been present for few
versions already and others seems to have spotted similar issue [0].

Steps to reproduce issue:
- Run 'emacs -Q' on OpenBSD X
- switch major-mode to org-mode
- run 'org-capture'
- select template 't'

After selecting template the emacs seems to freeze for a while but
completes if I wait enough. My inaccurate wall clock measurement seems to
give that first time running org-capture it takes about 30s. to
complete. Later runs seems to work a bit faster and complete in 16s.

Setting x-selection-timeout to 10 makes org-capture complete almost
instantaneously but this seems be working around the issue and not
fixing the root cause.
