Code reloading in Rails development stalls

[dysonreturns]

Hey :)

I've noticed that any code changes to Rails apps in development, i.e. modifying any controller code, makes all future requests hang. It stalls everything, even unmodified controllers.

Starting a puma server doesn't give me the same problem.

Is this a known limitation with falcon + rails/zeitwerk, has something regressed or is it just me?

Environment:
OS: macOS
Ruby: either 4.0.5 or 3.4.10
Rails: either 8.1.3 or 8.2.0-alpha
falcon: 0.55.5
falcon-rails: 0.2.4

Step to reproduce:

• I start a blank Rails app using all default settings.
• Bundler add falcon & falcon-rails
• Create a route and a controller+action which does anything.
• Start the server with falcon serve and hit the endpoint
• Then modify the controller code with any difference
• Hit the endpoint again. Any further requests are stalled, even default homepage

Okay, odd, let me take a look.
