Hmm... here on my 10 years old desktop running Debian stable it's more
like 0.03s.  If it's so slow even for situations where the users have
already typed `read`, ... hmm ... maybe we should try and make the
completion asynchronous or at least abort the `man -k` as soon as the
user types something, or add some level of caching...?
