The memory management of CopiedHandle was completely broken and beyond repair,
so we removed it. It may have worked for just exactly the case you used it for.
I have just started implementing a replacement, it may become part of the next
release (or the one after that).
For the time being, you could use a SharedHandle and always update it using
false as the share argument (false here only means no sharing between spaces -
the sharing within a space is always preserved!).
Would this be a workaround for your problem?
Cheers,
Guido
