Unregistering many thousands of kprobes can take several minutes.
(Registration seems to be quick.)
This could be because of extensive synchronization for each
inserted/removed probe. Please investigate whether such
synchronization could be done once for a batch of many kprobes.

Specifically, it seems to be the rcu synchronization after every unregistration
that takes so long when multiplied by thousands.
