Steve,
Did you recently run "upgrade catalog"? If so, the first time we upgraded our
catalog to support 11G databases, we had a couple of target databases
experiencing similar behavior. Below is my notes from where I resolved the
problem. Apparently I didn't take good notes, but I seem to remember seeing
"control file sequential read" events showing up in the targets database's
v$session_wait view.
=======
Symptom: RMAN full resync of recovery catalog takes extra long time.
FIX:
On Target Database:
SQL> exec dbms_stats.gather_fixed_objects_stats() ;
SQL> alter system flush shared_pool;
RMAN> sql "alter session set optimizer_mode=RULE";
RMAN> resync catalog
=======

More Info:
I'm backing up to tape
The target and the repository databases are both 11.1.0.7.0
I have crosschecked and deleted several times, only a few days of backups are
in the control file.
