svn rev #23138: trunk/src/tests/threads/

[raeburn@MIT.EDU]

http://src.mit.edu/fisheye/changelog/krb5/?cs=23138
Commit By: raeburn
Log Message:
Don't start by attempting to unlink replay caches by guessing
pathnames specific to my uid on MIT Athena systems.  Instead, create a
replay cache object and then destroy it through the library.  Tweak
the rcache-init-error messages to be specific to the instance that
failed.
