You can easily generate tags and cscope data in the background with
commands like these:

:!ctags -R &
:!cscope -R -b &

The problem is knowing when they're done. For that, you could do
something like this:

:!{ ctags -R; xmessage 'ctags done'; } &

Using grep is a little trickier because you usually want to read the
results into a quickfix list. For that, you could do something like
this:

!{ grep -Rn pattern . > ~/mygrep.out; xmessage 'grep done'; } &

followed by this when that is done:

:let &efm=&gfm
:cf ~/mygrep.out
