* to expose a home-grown event loop to verto.
*
* If deflt is non-zero and a default ctx was already defined for this module
* and ctx is not NULL, than ctx will be free'd and the previously defined
* default will be returned.
*
* If ctx is non-NULL, than the pre-existing verto_mod_ctx will be converted to
* to a verto_ctx; if deflt is non-zero than this verto_mod_ctx will also be
* marked as the default loop for this process. If ctx is NULL, than the
* appropriate constructor will be called: either module->ctx_new() or
* module->ctx_default() depending on the boolean value of deflt. If
* module->ctx_default is NULL and deflt is non-zero, than module->ctx_new()
* will be called and the resulting verto_mod_ctx will be utilized as the
* default.
*
* This function also sets the internal default implementation so that future
