[racket] Command line Racket equivalent of DrRacket's Racket | Run (CTRL+T or F5)?

To answer my own question: It looks I want
geiser-mode-switch-to-repl-and-enter. Great. That works close to what
I'd hoped.

Unfortunately I'm encountering a problem where sometimes Geiser gets
into a state such that switching away from the "* Racket REPL *"
buffer (with e.g. C-x o) will create a buffer named "*spurious*" with
contents like this:

-----

stdin::332: read: unexpected `)'
c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:57:15:
((current-read-interaction) (object-name in) in)
c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:56:2:
(let-values (((form) ((current-read-interaction) (object-name in)
in))) (let-values (((arg) (datum->syntax (....) ....))) (let-values
(((....) ....)) (let-values ....))))


 === context ===
c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:53:0
C:\Program Files (x86)\Racket\collects\racket\private\misc.rkt:74:7

racket at dns.rkt> stdin::333: read: unexpected `)'
c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:57:15:
((current-read-interaction) (object-name in) in)
c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:56:2:
(let-values (((form) ((current-read-interaction) (object-name in)
in))) (let-values (((arg) (datum->syntax (....) ....))) (let-values
(((....) ....)) (let-values ....))))


 === context ===
c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:53:0
C:\Program Files (x86)\Racket\collects\racket\private\misc.rkt:74:7

racket at dns.rkt>

-----

It's stuck in a state where every time I switch to the *Racket REPL*
buffer and away again, it will create yet another *spurious* buffer.
For instance *spurious*<2>, *spurious*<3> and so on.
