On my PI installation, I also have the issue of way too much CPU usage since yesterdag, the system is unusable since then.

I checked the logs, I found one error, but I think it is unrelated:
Unable to load libcurl.so.4, reason: /usr/lib/arm-linux-gnueabihf/libssh2.so.1: cannot read file data: Is a directory

=> I checked the file, and it was a hard link to the complete folder instead of to the correct file. I thought the correct file would be libssh2.so.1.0.1, so I updated it like this:

Terminal

xbian@xbian ~ $ sudo unlink /usr/lib/arm-linux-gnueabihf/libssh2.so.1
xbian@xbian ~ $ sudo ln /usr/lib/arm-linux-gnueabihf/libssh2.so.1.0.1 /usr/lib/arm-linux-gnueabihf/libssh2.so.1

But then I got this error:
Unable to load libcurl.so.4, reason: /usr/lib/arm-linux-gnueabihf/libssh2.so.1: file too short
