The problem gets weirder.  I got rid of the rm problem by renaming another
file to the same name as the first and then removing it.  But now:


[triffid:1:25pm:0]/coda > ls
users/
[triffid:1:25pm:0]/coda > cat > testfile
testfile: File exists.
[triffid:1:25pm:1]/coda > test -f testfile || echo not there
not there

I wrote little programs to open the file O_RDONLY, O_WRONLY, and O_RDWR.
In each case, open(2) returned -1 with errno set to ENOENT.  So how cat
thinks the file is there is beyond me.
