Exception in 'threadWait' after a while

I'm getting `threadWait: invalid argument (Bad file descriptor)` after a while when an endpoint has been triggered.

### Example code
```hs
{-# LANGUAGE DataKinds #-}
{-# LANGUAGE DeriveGeneric #-}
{-# LANGUAGE OverloadedStrings #-}
{-# LANGUAGE TypeOperators #-}

module Main where

import Data.Aeson (ToJSON)
import Data.Text as T
import GHC.Generics (Generic)
import Network.Wai.Handler.Warp (run)
import Servant (Application, Proxy(..), Server, serve)
import Servant.API ((:>), Get, JSON)

type ModuleAPI = "modules" :> Get '[JSON] [Module]

data Module = Module { moduleName :: T.Text }
deriving (Eq, Show, Generic)

instance ToJSON Module

mkModule :: T.Text -> Module
mkModule name = Module { moduleName = name }

modules :: [Module]
modules = [ mkModule "module#1" ]

server :: Server ModuleAPI
server = return modules

moduleAPI :: Proxy ModuleAPI
moduleAPI = Proxy

app :: Application
app = serve moduleAPI server

main :: IO ()
main = run 8080 app
```

### Steps to reproduce
1. Compile with profiling options
2. Start the application with `+RTS -xc`
3. Make a request against `http://localhost:8080/modules`
4. Wait for the exception stack trace to be printed to the console

### StackTrace
```

When adding a logger of some kind one can verify that the exception is `threadWait: invalid argument (Bad file descriptor)`. Is there anything I can do about this?
