Delete log while partition assistant sector by sector cloning in progress?

This is related to another post where I added onto an old thread about very large log sizes.  Currently, my computer is bogged down because all OS drive space has been taken by the Partition assistant log. 

If I use a tool to break the file reservation on the log can I delete it while the cloning process is running?  The cloning has been going very slowly (from 53% at 6am today to 64% by 3pm).  I don't want to loose the process but at the same time I'd like to be able to use the computer.

Please let me know whether I can delete the log while the sector by sector clone process is active.  To be clear, I don't want to crash the cloning process! 

Thanks!
