New devtool build this morning seems to hang on key import.  The last
thing I see in the standalone_testdrive log is:

++ /usr/local/bin/rpm -vv --import ./pubkeys/JBJ-GPG-KEY
D: opening  db environment /usr/local/var/rpm/db/Packages cdb:mpool
D: opening  db index       /usr/local/var/rpm/db/Packages create mode=0x202
D: locked   db index       /usr/local/var/rpm/db/Packages
D: opening  db index       /usr/local/var/rpm/db/Name create mode=0x202
D: adding "gpg-pubkey" to Name index.

Attaching gdb to the running rpm process shows this backtrace (snipped output):

$ gdb rpm 17308

Anything else I can do to help diagnose?  I can leave gdb and the
process running (it doesn't seem to be impacting performance at this
point).
