I have executed the program, using the same RTS flags as yours:
real 6m13.523s
user 0m53.931s
sys 0m7.812s
815 MB usage
This is an huge improvement!
Using UArray and empty + insert:
real 5m40.732s
user 0m58.620s
sys 0m7.264s
660 MB usage
Using singleton + union, memory usage is the same: 657 MB
So, now:
1) I don't understand why using uvector leaks memory.
I'm using the latest version found on Hackage.
2) Why your version of code, using singleton + union, consumes more
memory.
