Thank you! A simpler fix for WSL ghc users is upgrading to fast ring of
insider builds, the mmap overhead is much lower and ghc startup lag is
barely noticable.

I have made available a build of GHC 8.2.2 with the config option: --disable-large-address-space
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.
