I thought that might provoke you into commenting... :-) ISTR we discussed this very issue back when g_file_storage was being developed. I can't recall the actual issue or what we decided. It may had something to do with a desire to avoid allocating separate buffers for bulk-in and bulk-out. Do you think the code in file_storage.c needs to be changed?
