More info:

As per bug 25234, using 'M-! xdg-open /tmp/test.pdf', 'M-& xdg-open 
/tmp/test.pdf'
and 'M-& xdg-open /tmp/test.pdf && sleep 3' I get same results as reported.

If I try in eshell buffer 'xdg-open /tmp/test.pdf && sleep 3' my cursor 
blinks
with the Okular icon for a few seconds and then nothing happens.
