GHCi has some weird behaviour sometimes with one or more of these symptoms:
- becoming very slow and/or unresponsive
- gobbling up memory
- crashing with "thread blocked indefinitely on MVar"
Some people have reported this happening when they weren't even doing
anything, GHCi was just sitting at the prompt.
e.g. this ticket:
All the reports were Windows, but I've seen it happen on Mac too (but
I really need a way to reproduce this. If anyone has any clues, or can
offer any more information (even if it's just a "me too, on platform
X"), please let us know.
