lei: improve management around short-lived workers
Instead of creating a short-lived circular reference,
ensure they don't exist in the first place.
Note the following changes to hold an extra ref to $sto:
- $self->_lei_store(1)->write_prepare($self);
+ my $sto = $self->_lei_store(1);
+ $sto->write_prepare($self);
I'm not a perlguts expert, but I actually wanted to switch
to the one-line version for LeiImport, but xt/lei-auth-fail.t
was getting stuck for some reason. It seems the extra ref
to the LeiStore ($sto) object is necessary.
