[platform-ui-dev] Expensive to create SWT clipboard?

[Randy Hudson <hudsonr@xxxxxxxxxx>]

Is creating an SWT Clipboard expensive?
 In our code we are just instantiating the clipboard as needed, doing
something, and then disposing it.  So, I went to see if the platform
puts the dispose() in a finally {} block, but I found out that almost everywhere
clipboards are kept around with each part until the part is disposed.  Is
there a reason?

For example, BookMarkNavigator keeps
its clipboard around in a field.
