Have you considered switching to NIO with one io-loop thread per connection/several connections?
Something like Netty or Apache Mina.

It can result in creating too many threads.

Consider web appication scenario. It sends a message per incoming request. Requests are served from several threads (up to 100) with a heavy concurrency (hundreds requests per second). So application needs either thread-safe non-blocking publisher that is suitable for heavy concurrency or very light-weight non-thread-safe publisher that can be created per incoming request and deleted after use.
