What makes you think that it would take forever? Why would the  
program NEED to write to the CD?

CDs are indeed slower than hard-drives, but once the o/s &  
application are loaded into RAM (assuming an adequate amount) then  
disk access to them should not be required. The o/s & application  
should operate entirely from RAM & likewise sections of the hard-disk  
that are being defragmented should be loaded into memory & copied  
elsewhere on the drive (before being deleted, of course).

/Volumes is the directory into which diskarbitrationd mounts non- 
system drives & partitions. For instance, if I plug my external  
firewire drive into my Mac & type `open /Volumes/My_Firewire_Drive`  
in the terminal I will see the its contents in the Finder; if I mount  
a shared network drive by pressing Apple-k and giving the address  
192.168.1.43 then at the command-line I can copy I files to that  
share with `cp foo /Volumes/192.168.1.43`.

Although occasionally I'll find empty directories in /Volumes, left  
after a network share has been disconnected by putting my Mac to  
sleep, these are always cleaned out next reboot & I have no idea why  
your actual disk images size have been left in this directory.
