Hi,
First of all, don't be fooled by the alloc statistic. That is not 3GB
memory residency, that's 3GB allocation, which was interspersed with
lots of garbage collections, in the same way that measuring how many
times malloc was called in a C program doesn't necessarily indicate
memory

Indeed and writing the t+1 strictly to the ioref also makes it
slightly faster (~2%):
writeIORef ioref $! t+1
