Martin,
We recommend an import use its own MOC, and simply set the undo
manager on the MOC to nil. Easier, better, less filling.
MOC are not particularly expensive to create, so if you cache your
PSC, you can use different MOCs for different working sets or
distinct operations.
Just to be very clear, Ben: I read this to mean that it's fine to
have multiple MOC's in one thread for a given PSC. Right? MOCs
should not be shared across multiple threads (per documentation), but
I gather that the converse is false.
