When you press and hold Ctrl-c, after a few seconds, sometimes \> 60 sec, GHCi crash and we can read a message on the screen (of the console) who says: ``` ghc.exe : failed to create OS thread ``` On the task manager we can read: ``` ghc memory : 36920K ``` initially, then the memory grows about ``` ghc memory : 43480K ``` and stay until the crash. I repeated it several times. With Linux if you repeat this, GHCi do not crash. Idem with only the Windows console.
