Ouch.  So there *is* indeed something special about $cgihash:  It is
a tied hash, tied to the CGI object itself.  That's how Vars happens
to be implemented in CGI.pm.

Tied variables behave strange in some aspects, and I guess this is one
of them.  I think that TT gets stuck when trying to find out whether
cgihash is an object which implements a 'keys' method or a hash which
should respond to the 'keys' vmethod.

You should be able to get rid of the nuisance by copying your cgihash
to an explicit hash before use.
