Sebastian Spaeth b81b7d6001 Implement true single-threading
Previously, we would spawn child threads for account synchronization
even if we had single-threading enabled. This prevented us from catching
the true location of exceptions, for example. Now, in single-threaded
mode, we perform the account synchronization truely in the main thread
which will ease our debugging.
