Comment (by ocharles):

 I should point out that the exact same code doesn't fail when we run it on
 bare metal, so it seems to be something specific to running in QEMU. This
 also doesn't always happen, but it certainly feels like it happens more
 often than not. We're building this executable with:


 {{{
 ghc-options: -Wall -O2 -threaded -rtsopts
 }}}

 We run the server with:


 {{{
 ${metronomeConfig.package}/bin/metronome-server -c
 ${config.services.fynder.configFile} +RTS -k1M
 }}}
