It might. Using `pp' was dropped for writing cache data, but it is still
used for index.eld file (I was hoping to keep this file readable).
If we come to the point when index file is causing significant slowdowns
and cannot solve the slowdowns in any other way, `pp' can be dropped
completely.

Thanks!

356 16% + rename-file
267 12% + write-region
I added that call to `rename-file' attempting to fix
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=75209, but the bug is
still there, so things are not quite as simple.

That's a bug in org-roam. Such advices should be written extremely
carefully because they are affecting low-level operations.

org-persist only writes of org-persist-directory, but the org-roam's
advice does not appear to be very selective.

You were not subscribed, so your email had to go through human
