/* Our pool can have two kinds of errors:
- Parsing or connection error
Those are fatal errors (we drop the connection if we encounter them).
After they are constructed from const char* strings from various places.
(can be from read-only mem), we passs them in an exectutor message
once the recv thread expires.
- Call error
This error happens when the "server says no". Usually because the job was
outdated, or we somehow got the hash wrong. It isn't fatal.
We parse it in-situ in the network buffer, after that we copy it to a
std::string. Executor will move the buffer via an r-value ref.
