I think there is a sign error in `org-persist--refresh-gc-lock` that prevents
old sessions from ever expiring from `gc-lock.eld`.
In Org 9.7.11, the relevant code is:
```
(dolist (record alist)
(when (< (- (float-time (cdr record))
(float-time (current-time)))
org-persist-gc-lock-expiry)
(push record new-alist)))
```
`org-persist-gc-lock-expiry` defaults to one day. However, for any record
whose timestamp is in the past,
```
(- (float-time (cdr record))
(float-time (current-time)))
```
is negative, and is therefore always less than the positive expiry value.
For example, a record that is 100 days old gives approximately
```
-8640000 < 86400
```
so the record is retained instead of being discarded.
I noticed this because my `~/.emacs.d/org-persist/gc-lock.eld` currently
contains 147 session records, although only 3 Emacs processes are running.
There are also 41 files under `org-persist`, while only 16 `:container` entries
in `index.eld` refer to persist files. Thus a substantial number of orphan
persist files have accumulated.
This also appears to prevent orphan-file garbage collection. `org-persist-gc`
only collects orphan files when `org-persist--gc-orphan-p` determines that
there are no other active sessions. Since stale session records never expire
from `gc-lock.eld`, that condition may never be reached.
It looks as though the test should instead be:
```
(dolist (record alist)
(when (< (- (float-time (current-time))
(float-time (cdr record)))
org-persist-gc-lock-expiry)
(push record new-alist)))
```
That is, the operands of the subtraction should be reversed.
I also checked the current Org source and, unless I am overlooking something,
the same expression is still present there.
Could you confirm whether this is a bug?
