Work around problem with asynchronous polling calls from AppleShare FST. 

This patch disables asynchronous SPCommand calls to work around the problem, which was causing hangs and crashes when those calls triggered. This effectively prevents the FST from automatically polling to check if the volume has been changed, but shouldn't cause other problems.
