Thank you for reply.
I changed forkIO to forkOS. But I received the following error.
ERRORCannot create OS thread.
I want to decrease the stack size of threads to increase the number of
threads to be created. How can I do this?
I tried to decrease ResourceStackSize and tried the RTS -k option but
both does not increase the number of threads...
