no error hang 'Applying configuration' in case of aplication error

[SailorMax]

Unfriendly behavior in some cases.

steps:

1. create sample express-application (nodejs) from unit's examples inside docker container
2. setup arguments as ["nodemon", "--loader", "unit-http/loader.mjs", "--require", "unit-http/loader", "src/server.js"]
3. docker up

expected: Some kind of error message, like "Can't start application because 'Failed to create Unit object'"

actual: init process hang on step 'Applying configuration /docker-entrypoint.d/config.json' Unit's logs has the error:

[alert] 24#37 [unit] mmap(11) failed: No such device (19)
/usr/local/lib/node_modules/unit-http/http_server.js:406
    this.unit.createServer();
              ^

Node.js v20.6.1
Aborted

P.S. Looks like unit doesn't support nodemon. With regular node it works fine. But current problem in silent errors!

Using: unit:1.31.0-node20

Hi @SailorMax thanks for sharing this with us! We are having two more NodeJS releated issues. I will add this one and will come back to you asap!
