Comment (by kvelicka):

 I'm currently working on adding such functionality. In the current state
 of affairs, the problem isn't that the log is not being dumped, it's being
 written to continuously. The issue is that the release version of `ghc-
 events` cannot parse incomplete `.eventlog` files. My WIP version of the
 library does, so if there's a need to profile something urgently, feel
 free to try it out: https://github.com/kvelicka/ghc-events . Working on
 this is now a part of my university project, so it should hopefully be
 finished up and merged into the master branch soon.
