Oh, so it's a problem with 'timeout', not a bug in 'grep'?

What does 'timeout 1 sleep 2' do? It should exit with status 124 because of the 
timeout. If it exits with status 0, it's a bug.


What do the following commands do? They are how require_timeout_ decides whether 
'timeout' is working.

( timeout 10s true ) > /dev/null 2>&1
echo $? # echoes "0" if 'timeout' works

timeout 10s false
echo $? # echoes "1" if 'timeout' works


Perhaps all we need to do is change require_timeout_ so that it excludes the 
broken 'timeout' on Alpine 3.10; e.g., require_timeout_ could check that 
"timeout 0.01 sleep 0.02" exits with status 124.
