Why do you think that? We clearly agree that deleting PWD works.
What is the problem? If you were omniscient then you would have done
so long ago, but of course none of us are.

The "fix," "as it's been coded," is obviously a workaround for an end
user that wants the correct behavior immediately, without recompiling
P4.so. The actual fix would be to p4.cpp. However the workaround
shows exactly what to do: delete PWD from the environment, call into
perforce, then restore PWD if it previously existed. If there is
something wrong with this plan then please tell us.
