  • Fix two space leaks while compiling many modules

    The first would interleave compilation of too many modules at once, which would increase memory usage, especially for single threaded builds with +RTS -N1 -RTS. Now the number of concurrent modules is limited to the number of threads available to the GHC runtime system.

    The second would hold on to memory from modules that compiled with warnings until the end of the build when the warnings were printed and the memory freed. This is now fixed with additional NFData instances.
