Look at back-bdb/tools.c; slapcat creates a pseudo-op in back-hdb mode. There
are a couple of different "ctx" fields in the operation, it's not clear what
you're talking about. Of course, it's a moot point - the threadctx will be
retrieved if it's needed and not provided, and the tmpmemctx is purely
optional. If you don't provide a tmpmemctx then mallocs will all use regular
malloc instead of temporary memory.
