We have a memory ccache type, which you can use by setting a credentials
cache name of MEMORY:somestring, where somestring serves to
differentiate memory ccaches within a process.

These caches cannot be shared between processes.  I believe that makes
it tricky to use one transparently, since a credentials cache is
ordinarily shared between kinit (to initialize the cache with an AS-REQ)
and an application.  I have not looked into this myself, but I believe
you would have to write application code to pull a TGT out of a normal
(say, file-based) credentials cache and copy it into the memory ccache.
