Cloning a template while deleting several machines throws ManagedObjectNotFound

[yairfrid]

This occurs every so often in my codebase, sometimes when deleting a few machines at once, and then cloning a machine(simultaneously), this exception is thrown and the machine is not cloned.

pyVmomi.VmomiSupport.ManagedObjectNotFound: (vmodl.fault.ManagedObjectNotFound) {
   dynamicType = <unset>,
   dynamicProperty = (vmodl.DynamicProperty) [],
   msg = "The object 'vim.VirtualMachine:vm-58107' has already been deleted or has not been completely created",
   faultCause = <unset>,
   faultMessage = (vmodl.LocalizableMessage) [],
   obj = 'vim.VirtualMachine:vm-58107'
}
