rdir.c isn't reporting any problems on the server at the same time the NFS
client is malfunctioning badly...

On the server:

FreeBSD login.peregrine  bacon ~/Data/TOPMed/Jobs/Haplohseq-analysis 1030:
./test-rdir AD-VCFs-whi/MAF-0.01-1000nt/ |& tee rdir.out
............................................................................................................................................^C

FreeBSD login.peregrine  bacon ~/Data/TOPMed/Jobs/Haplohseq-analysis 1031: cat
test-rdir 
#!/bin/sh -e

usage()
{
    printf "Usage: $0 dir\n"
    exit 1
}

if [ $# != 1 ]; then
    usage
fi

# AD-VCFs-whi/MAF-0.01-1000nt
while true; do
    ./rdir $1
    printf "."
    sleep 1
done

On a client:

FreeBSD compute-009.peregrine  bacon ~/Data/TOPMed/Jobs/Haplohseq-analysis
1002: ./test-ls AD-VCFs-whi/MAF-0.01-1000nt/

These should all read 11031:

   11029
   11024
   11035
   11031
   11029
   11034
   11028
   11032
   11031
