OK, so ... Loading a file in the #keybase filesystem in my #emacs takes FOR EVER. The culprit is projectile, because emacs -Q is fast and emacs -Q after loading projectile is slow. Adding /keybase to vc-ignore-dir-regexp doesn't seem to fix it.
Any suggestions on how I can find out what part of projectile is so slow, and how to fix it?
