rename test so it always runs
new exceptions
single place for directory logic at FS level
stream review/robustness. Output stream includes abort -purely experimentally-
crank back logging to keep passwd out of log output
retry, timeout and public config options
minor reformat
log when tests are being skipped
test delete operations
new directory logic (broken)
Lots of work on getting the tests to pass; much -but not all- of the FS contracts are being met
