SERVER-8741 make sure we contact from-shard at least once after commit
SERVER-9621 Add getBuildInfo() function to shell
SERVER-9621 Disable jstests/dur/closeall.js on 32-bit Windows

This test fails frequently on 32-bit Windows due to remapPrivateView
being unable to remap a file when another thread allocate memory
while a file is unmapped.

Disable the test in 32-bit Windows since this can't really be fixed
without changes to the storage layer (and 32-bit does not benefit
from stress testing).
SERVER-9621 Fix case for 32-bit windows test.
