OOM on Travis for store-0.4.1 on GHC 7.10.3 while building Stack

[Blaisorblade]

In the past few days I've noticed a few failures like the following, mentioning OOM
https://travis-ci.org/commercialhaskell/stack/jobs/234558520#L321-L324 (https://travis-ci.org/commercialhaskell/stack/jobs/234737983 was also one, but I had to restart it).

Building stack took lots of memory in other situations. Can anything be done to improve the situation? (I'd be open to workarounds on the stack/Travis side).

This one fails on this file:

Other failure in https://travis-ci.org/commercialhaskell/stack/jobs/234811762, it seems on Data.Store.TypeHash.Internal.

Version 0.4.3.1 has quite a bit fewer uses of INLINE, which will likely help with that issue.
