By mistake I sent the message below as private one at first. However it 
actually does not add anything new to my previous comments to the bug.

Yes, I am. It is about proper way to a launch viewer in 
`mailcap-view-file'. Original `start-process-shell-command' with 'pty 
connection type prematurely kills children of kde-open5 or gio open. 
With 'pipe connection type it or `make-process' might make emacs CPU 
hungry if a child decides to close stdout and stderr:

>> #!/bin/sh
>> exec 1>&-
>> exec 2>&-
>> sleep 30

and finally `process-file-shell-command' does not allow to report 
failure. Moreover you suspect another secret compatibility problem with 
'pipe.
