Digikam Thrashes Fedora

When downloading files from a camera (Canon S5IS), Digikam
apparently reads each file into memory, then writes it to disk.
This works well as long as the picture files are small.

When the file is larger than free memory, Fedora pages quadratically.
The newer cameras can generate files up to 4GB on their FAT32
chip file system.  A 4GB system loads a 2GB file in a few
minutes.  Fedora FC9 Beta 64 on a 2GB Core Duo took more
than five hours.  The disk was thrashing. 

Apparently Digikam needs an alternate method of file transfer
for large files.
