Image Capture Extension

Question

Has anyone noticed that with Aperture 3.6 and  Yosemite, when Aperture is launched it invokes a process called "Image Capture Extension?" This process can use quite a bit of memory. When Aperture is quit, the process remains. When Aperture is launched again, the process consumes more memory, which remains in use even after Aperture is quit again. At some point the memory consumption can apparently have a significant effect on performance of a machine, especially if memory is in short supply.
This surely is a bug of some kind, Has anyone noticed this and reported it?

Answer 1

I've no explanation but I'd like to add that I've seen this extension monopolizing up to 16.5 GB of memory.  That means that it's taking all my RAM or else requiring a very large amount of information to be swapped to disk.  Either explanation is bad, as either one will slow the machine.  I thought that I could quit this process without causing a problem, but after I did that a scan took about two minutes for a single page of text.  When I looked, Image Capture Extension was running again, but it was taking up 3.3 GB of memory. The next scan went smoothly, but the Extension never relinquished any of that memory. Neither, however, did I see it increase its memory hogging further after another scan.  I'm perplexed.  I don't think this extension's excessive memory use is harmless.
It uses the same icon as many OS X system processes (SymLinker, SystemUIServer, SIMBL Agent, etc., etc.), so I think it's developed and distributed by Apple, itself.  Seems as though someone from Apple could jump in here to explain what it is and what to do about the memory hogging.
