Obvious candidate from the commit log is 73ebb92e9df01ba7afb97121b6e2cef6ca13a18e - use thread_group for improved exception safety

Added some logging in encode-servers branch.

Saw a hang a fair way into a long DCP encode with a Linux host and a linux encode server. No useful backtrace, unfortunately.

j2c and pcm were written to the DCP so it looks like something happening when the main encoding bits are torn down and the metadata writing starts.

Reporter suggests that 2.15.111 might have sorted this (though my hang was on a git version after 2.15.111)
