[developers] Mysterious Japanese grammar hang

More specifics on this bug:
I used to have the Japanese grammar under the following path:


This used to be fine, but suddenly it stopped working in the manner
described upthread.

Francis fixed this problem by moving the directory to:


It is not clear why this should have fixed the problem.  The one interesting
thing about the file system is that the corpora directory on my machine
contains many softlinks:

$ ll ~/corpora/
total 5
lrwxrwxrwx 1 billmcn billmcn 36 Jul 22 17:23 LDC-parses ->
drwxr-xr-x 3 billmcn billmcn  3 Feb 17 17:14 Tanaka
lrwxrwxrwx 1 billmcn billmcn 22 Jul 22 17:23 treebank-2 ->
lrwxrwxrwx 1 billmcn billmcn 21 Jul 22 17:23 treebank-3 ->
lrwxrwxrwx 1 billmcn billmcn 39 Jul 22 17:23 wsj ->

This targets of these softlinks exist, but the softlinks were broken,
presumably because of some recent NFS changes on our system.

This is not a problem with the Japanese grammar or DELPH-IN tools, but it
may be useful to keep this in mind as a way in which NFS problems may hurt
the functioning of these tools.
