vmwarereqtool freezes and never return to the prompt after is executed

When trying to generate the VMWare requisition from vCenter using the vmwarereqtool commands. It doesn't matter if the execution of the command was successful (i.e. the requisition was generated), or it an exception is thrown (i.e. authentication errors, for example). The command hangs after that, and it must be terminated manually by issuingCtrl+C.

This is new behavior as that was never the case when that command was introduced.
