I have made available a build of GHC 8.2.2 with the config option:

You may find this useful if you are using Ubuntu 16.04 on Windows
Subsystem for Linux.


Although Microsoft has been making gradual progress on the large
address mapping issue[1][2], and the situation is much improved, there
is still an extra startup latency of about 13 secs. for applications
that pre-map a large address space as GHC does by default. This makes
the standard GHC 8.2.2 binary unusable for compiling projects of any
non-trivial size on WSL. You may find this GHC 8.2.2 binary more usable.
