GHCi leaks the first modules loaded
How to reproduce the leak:
cd nofib/real/veritas
ghci +RTS -S
Prelude> :load Main
*Main> System.Mem.performGC
10554832 32639712 38824584 0.048 0.058 2.317 8.386 0 0 (Gen: 1)
Live data is ~38Mb (3rd number). Now unload everything:
*Main> :load
Prelude> System.Mem.performGC
4005376 32681280 38850224 0.013 0.048 2.330 29.896 0 0 (Gen: 1)
Note the live data didn't go down.
Load the program again:
Prelude> :load Main
...
*Main> System.Mem.performGC
16344112 47790304 54799632 0.070 0.074 4.343 82.235 0 0 (Gen: 1)
Note the live memory is almost 2x what it was before.
