The work around is to disable saving caches, as they may not be correctly saved. However you do not have access to change the settings for the system CFs. I imagine it may only be an issue if a node is rebooted as it may load stale caches.
I think it's windows only as the function used to rename the saved cache says it has different operation on different OS's http://download.oraclecom/javase/6/docs/api/java/io/File.html#renameTo(java.io.File) and there seems to be a number of people complaining about the behavior on windows.
On my ubuntu desktop I ran a test where a user CF safes it's caches every 5 seconds and all was well.
32bit Win XP (sp3) may not fall into the list of supported OS's for cassandra, but we may confirm how it works on a more modern Windows version.
Let me when you have created the bug.
Thanks
Aaron

I have a question. How do you think this happens only on windows(on this platform i don't worry, because this is only test platform) or everywhere (linux)? And how dangerous this error, or at first time i may simply ignore it?

Ruslan can you please raise a bug against 0.7.2 for this and include the platform.
You mean in JIRA?
This happens on WindowsXP (SP3) 32 bit
