R15 beachballsl when relinking media after XML import

Import FCPX XML
media is online, a couple TLs 4-5 min long maybe 150 clips per TL, a few hundred total in project
after XML imports, and R starts to do its thing, it simply beachballs.
at first I thought is was a hang of some sort. I left it for a good 2 min. then I opened iStat. R was using 27% of one core steadily. looked at disk activity for volume media was stored on. constant bursts of 25mb/sec reads. clearly something was going on.
I left R to run for a good 10 or maybe 15 min and it finally completed, all was well.
So, whatever it was busy doing - maybe generating audio waveforms, inspecting the media, whatever a Progress Bar is in order to let the user know the app isn't in a hang state.
10.13.6 release, 396.x drivers, Titan X, 64gb ram, 3.46ghx X 12/24
