Ignore ERROR_WAIT_NO_CHILDREN issued by WaitForSingleObject

ERROR_WAIT_NO_CHILDREN means a thread was killed (lane terminated because of error raised during a linda transfer for example) while having grabbed some mutex
this seems not to be a big problem as we will grab it just the same, so ignore this particular error
