The kadm5 unit tests reveal the following memory leaks, apparently in
the RPC:

This memory was allocated from:
_malloc [malloc.c:761]
create_client [svc_auth_gssapi.c:841]
_svcauth_gssapi [svc_auth_gssapi.c:390]
_authenticate [svc_auth.c:103]
svc_getreqset [svc.c:448]
kadm_svc_run [ovsec_kadmd.c:440]
main [ovsec_kadmd.c:384]
__start [crt1text.s:133]
Block of 48 bytes (22 times); last block at 0x103d7348

MLK: 1007 bytes leaked in 19 blocks
This memory was allocated from:
_malloc [malloc.c:761]
make_seal_token [k5seal.c:67]
kg_seal [k5seal.c:322]
krb5_gss_seal [seal.c:46]
gss_seal [krb5_gss_glue.c:402]
auth_gssapi_seal_seq [auth_gssapi_misc.c:197]
_svcauth_gssapi [svc_auth_gssapi.c:691]
_authenticate [svc_auth.c:103]
svc_getreqset [svc.c:448]
kadm_svc_run [ovsec_kadmd.c:440]
main [ovsec_kadmd.c:384]
__start [crt1text.s:133]
Block of 53 bytes (19 times); last block at 0x103c7148

There are other leaks that lose 1-200 bytes over the course of the
KADM5 unit tests; see lib/kadm5/unit-test/kadmind.pure.pv in the build
tree on beeblebrox.

I'm not convinced these are actually memory leaks. I killed kadmind
after the tests had completed, so perhaps these are just the client
entries that were still in memory at the time.

Of course, I think all the clients are disconnecting properly so they
shouldn't leave entries lying around...

I no longer believe this is a memory leak.
