Invalid GLOBUS_HOSTNAME causes globus-gass-server abort.
globus-gass-server do not error and return safely.

I don't know this is the valid usage, changing GLOBUS_HOSTNAME.
But, I think globus-gass-server should return by error, or 
ignore the value of GLOBUS_HOSTNAME.

In my application, I prefer globus_gass_server_ez_init() error and return
if the invalid GLOBUS_HOSTNAME was given.
  (Our application uses GASS for Pre-WS GRAM support, our older usage of GT.
   Our application do not use GASS for WS GRAM support though.)
I don't need my application abort().

This problem occurred on GT4.0.1 and GT3.2.
This problem did not occurred on GT2.4.3.

This problem occurred on Linux x86, IA64.
This problem did not occurred on Solaris.

I'm setting environment variable MALLOC_CHECK_=2 on Linux.
