Well, I was wrong. It was different. The script hangs at 
"mount -a -tnfs"

After some testing, I think I figured out what went wrong and the errors
are reproducible.

At system boot time, when "ifup -a" is run, it brings up eth0 and then
tries to execute /etc/network/if-up.d/mountnfs before eth0:0 is up.
Well, in my case, the nfs directory is not accessible from eth0 but only
from eth0:0, so the script hangs at "mount -a -tnfs". I worked around
the problem by switching eth0 and eth0:0. Now everything works. 
BTW, the dangling /var/run/network/mountnfs was left behind because
at some point I used "CTRL-C" to kill the hanging script and I didn't
realize even the existence of the lock directory at that time. 

I don't know if there is a way to make the script wait until
all interfaces are up and running. In any case, this issue needs to be
resolved as on a multi-interface system, the script has no way of
knowing which interface should be used to access the nfs directory.

Best,
