Quite a number of pieces of my code have stopped working since then, but the one that's really a pain is the ASIO piece. I have a lot of code that makes use of ASIO's async read/write and other calls and there seems to be a problem reading data from socket with async_read_until - sometimes I get empty string, there's valid data at other times.

Consider that the buffer you are passing to your async calls has to
survive the handler.
How many threads are running the io_service::run ?
Consider that boost::asio::sockets are not multithread so only one
thread at time can call the async calls on it.
Can the handlers running concurrently ? If not you have to use the
strand.
