"Others" is apparently Drew, because wasamasa told you to report this to 
Projectile.

Projectile uses call-process-shell-command, which runs the process 
synchronously. It could switch to using start-process-shell-command, or 
at least provide an option to do so, to run the tags regeneration 
asynchronously.

That would raise the question, however, of properly notifying the user 
when the process has finished.

Nothing to do here in Emacs, closing.
