Memory usage grows roughly rapidly and monotonically. Since the original post, I have modified the Win32::OLE module on my machine to also delete the SAFEARRAY associated with Variants that have the VT_ARRAY and VT_BYREF flags set. Of course this contravenes the appropriate usage of the VT_BYREF, but when I use that module with this code, the memory usage is stable.

So it seems to me that it is possible to create a variant with the VT_BYREF flag that is the actual owner of the data. This should not be the case, as the whole idea of the VT_BYREF is that some other data structure owns the data and will take care of its cleanup
