In pathological cases (very old branch) this can take a couple of hours.
It should be noted that the server is located on the other side of the
world, but checkouts etc aren't that slow.

We have upgraded the clients to 1.5.5 just for this reason, server is
still 1.5.4. We deleted all mergeinfo from trunk, not without a certain
uneasy feeling I might add - we think we understand what we are doing
here but .... We have not yet verified if it makes a big difference,
most of the feature branches we integrate still have the old mergeinfo.

This brings me to a nagging question: Was it wrong to remove also the
"root" mergeinfo in trunk? Trunk itself will of course never be merged
back into something else.
