FWIW, I opened up a 5 MB text message (approx. 3.5 MB un-base64  
encoded) using IMP 4 and IMP 5.  This is a message that exceeds the  
maximum size filter, so there is only an option to download the  
message.  According to the memory stats from the debug log, IMP 4  
required approx 26 MB to download and IMP 5 required approx 16 MB.   
However, I have no idea how much of this is attributable to streams  
vs. previous improvements in the code (IMAP, MIME, IMP, etc.)
