I only adopted tmpfs, and the I/O block of pengine was improved.
I confirm the synchronization with the fixed file, but think that there is not the problem from now on.
It becomes one means to solve this problem to adopt tmpfs.

To Andrew : 
 If you make a patch removing a block of the file handling of pengine, I confirm the movement.
 If a problem is evaded without using tmpfs, many users welcome it.
