unrelenting coreservicesd process occupied CPU@92% and temp at 96ºC

I started up my mbp, logged in and loaded mail, safari and what not as usual. Having just been turned on, I thought it a bit odd that it as cooking up to 92ºC within minutes. Then I noticed via my iStat menu running on the top bar that CPU usage was committing 92% usage to coreservicesd (Core Services Daemon). I kicked on the fans, propped it to vent the underside and tried to figure out what coreservicesd was. 15 minutes later, 92% of the CPU was still taxed by coreservicesd. I couldn't find anything in the session log. Did a restart and everything works as normal.

So, any insight as to what coreservicesd was doing and why it got seemingly stuck?
