You could set the purgatory size to greater than the number you plan to insert, but I doubt that you have that much memory.
What you want is probably to make the puts synchronous. That is, you'd like the thread doing the inserts to wait until the insertion is complete to return (if the buffer is full). To do this, you can configure the disk cache to use a pool type event queue. Configure the pool to use a queue and set the when full policy to RUN. http://jakarta.apache.org/jcs/IndexedDiskCacheProperties.html There is another property of the thread pool called "whenBlockedPolicy" that is not on the site docs. Set it to "RUN".
