Comment(by Jafet):
Hi again. The previous message is incorrect; I didn't know that
{{{ghci.exe}}} always uses a child {{{ghc.exe}}} process.
What really happens on Windows is that {{{ghci.exe}}} is right away killed
by {{{^C}}}, and the child {{{ghc.exe}}} doesn't realize that until a
little later, so it goes into a panic. They also spawn some new threads
before they die for some reason. I've attached a trace by Process Monitor,
which records the syscalls made after {{{^C}}}.
Someone with a Mac could {{{ktrace}}} to check that it's really the same
bug.
