Note that 'delay' uses the 'threadDelay' function internally. AFAIK,
this function is only supported in GHC. So to build the module you
need GHC anyway which already supports the UnicodeSyntax language
extension (since 6.12.1).

I do agree that the dependency on stm is unfortunate. I will see if I
can put the modules Control.Concurrent.Thread.Delay and
Control.Concurrent.Timeout into a separate package. Any naming
suggestions? unbounded-delays or something?
