krb5_sendto_kdc fails in some threaded applications

[Simon Wilkinson]

I've been doing some further work on Kerberos integration in assorted  
applications, and I'm seeing some problems with the Gaim 2.0.0 betas  
and Kerberos 1.5.

It would appear that something in Gaim's threading is causing the  
select in the middle of krb5_sendto_kdc to return EINTR, which is  
causing the entire ticket request operation to return with an unknown  
realm error.

This has already been reported in RT (#5440), but I thought the  
problem was worth noting in case others are also banging their heads  
against it, in either this or other applications. The symptom is that  
a TGS_REQ will be sent to the first KDC in the list, but the  
application won't wait for a response, or contact any other KDCs.

Cheers,

Simon.
