Twainbridge taking up LOTS of CPU

Am I the only one to notice that after upgrading to DT 1.5.3, that twainbridge goes nuts on CPU resources? It just goes and goes between 20-90% of CPU usage. If I try to quit twainbridge, my computer becomes totally unresponsive, although it is still operating, my cursor does not move or keyboard work. It only happens when I have DEVONthink open.

This may not be any fault of DT, but it is only associated with DT. Any suggestions?
