#248 posix/fcntl runs ok once, trashes bash?, rerun fails

[Charles Evans]

on kubuntu 64bit: tried r5184, r5210
Once through, all posix tests run ok.
After tests run, bash has a problem:
touch test.tmp
rm -i test.tmp
rm: remove regular empty file 'temp'? rm: error closing file
# ^ file is not removed, not waiting for a reply.

$UNICON fcntl
./fcntl
Read failed: Resource temporarily unavailable

workaround for shell: restart bash, or:
sudo bash
exit
# ^ now rm -i test.tmp # works

ubuntu focal:
snapshot 9/6:
rm works
./fcntl && echo ok
Read failed: Resource temporarily unavailable
ok
(works)
rm works
make
(fcntl still works)
rm works
ok to close this.
