I am using 1.6 right now, but in the past I always used a current 1.5.

I do not think there even is such a thing as a global system lock to
grab, and Subversion certainly does not use one. Also consider, that
JNI happens everywhere when using Subclipse. Getting decorators,
showing history, everything. Do they all have this pause?

If not, then what is different about update? Maybe the pause is some
kind of filesystem level problem when SVN is crawling the WC. Do you
have an aggressive A/V solution that might be intercepting every file
open?
