> Description:
The quota command hangs if
1. NFS server is down
2. Root nameservers are not accessible (Internet connection failure) and automounter \
is running If quota is executed in /etc/profile, users cannot login (or have
to wait for logn timeouts). Each execution of quota on system with
automounter generates unnecessary requests to root nameservers 
(to resolve address 'pid250@machine').
> How-To-Repeat:

> Fix:
problem #1: use non blocking version of getmntinfo()
problem #2: don't try to call rquotad and resolve automounter \
pid(pid250@machine:/pub) in getnfsquota()
