Phil, I've released 5.7.1 now using 44b7b88. That means the 400ms delay remains in that version but everything else should work.
The crow-bar thread has been removed in current master (01482bf) so that should no longer show the 40s delay. The problem was that the 400ms delay was masking a race condition between the main thread and the crow-bar thread. Removing that delay meant that sometimes the crow-bar thread was missing the notification to shut down.
Regards, David

David,
As Rob says, I am using Linux (4.13.12-100.fc25.x86_64 from Fedora 25 updates).
I have tried the updated version (ga24f39a) and this fixes the issue. ProofPower builds in the expected time.? However, I have tried a few more tests and find that some compiled applications are very delayed on exit.? In the simplest Hello World GTK application, if it is open for more than about 3 s before being closed, it will take at least 43 s to close.? (I assume that is terminated due to the crow-bar thread.) Oddly, another Hello World GTK demo (based on GApplication) doesn't exhibit this behaviour.
I agree that it is a bit late in the release cycle to address this and don't see the half second delay on exit being particularly problematic generally.
