We randomly receive this error in our polling log:
"Could not create directory 'c/Documents and Settings/cmbuilder/.ssh'."

I'm pretty sure this is an error coming from Git, but it silently crashes the polling thread and the only way to get it running again is to bounce Hudson. I'm going to try restricting the # of concurrent polling operations to 1 to see if this resolves the error, as I suspect it is a problem with concurrent Git operations. However, it would be nice if the plugin caught this somehow and did not allow it to crash the polling thread for that Job.
