[DGD]Inherit_Program called twice?

[Kevin N. Carpenter]

I have a stripped down mudlib I'm using to develop my object manager and
have just spent the last hour trying to figure something out.  It appears
that the driver function "inherit_program" is being called twice during an
object compilation.  I highly suspect this is something in my code, because
that doesn't make any sense, but I sure can't find it.  Only 4 objects are
involved: The driver, inheritable auto, object user, and inheritable by user
userbase object.

The driver object forces a compile of the auto object.
The driver object forces a compile of the user object.
The user object inherits a file called userbase which forces a call to the
driver function inherit_program().
The inherit_program() forces a compile of the userbase object.
That compile finished, along with some book keeping.
** Then, to my surprise, it appears that inherit_program() is called in the
driver a second time for the same file, user, for the same program,
userbase. **
Since userbase is already compiled, this finishes quickly, but it still
seems odd.
I scanned all my code, it definitely DOES NOT call inherit_program directly.

Any ideas?  This is running under Redhat Linux 6.1 on an Dual Processor
server.

The trace below contains both function call traces and some object
management traces.
