The pattern
(ephemeron-value
(hash-ref! intern key
(lambda ()
(make-ephemeron key (wrap key)))))
is wrong, because a GC might happen between the time that the
epehemeron is found in the table (or the time that the key was just
added to the table) and the time that `ephemeron-value` is called to
extract the value. If the key is not otherwise accessible, the value
may no longer be in the ephemeron.

This is the source code for the core of Racket. See "INSTALL.txt" for full information on building Racket.
To build the full Racket distribution from this repository, run make
in the top-level directory. To build minimal Racket, run make base.
The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.
