Deno cache directory lock contention failure

[lrowe]

Came across this writing tests which are run with deno. Not a problem when I remove kvmserver from the mix and run the deno subprocess directly. I assume we must be missing some functionality here in the way file locking is implemented.

$ deno
Deno 2.3.5
exit using ctrl+d, ctrl+c, or close()
REPL is running with all permissions allowed.
To specify permissions, run `deno repl` with allow flags.
> using proc = new Deno.Command("sh", { args: ["-c", `exec /home/lrowe/devel/kvmserver/.build/kvmserver --allow-all --  deno run --allow-all --v8-flags=--single-threaded 'data:,Deno.serve(() => new Response("Hello, World!"))'`] }).spawn()
undefined
