I did a quick scan of the instruction set myself and it did appear 
useless, must be the GCC port it's brand new and the code generated 
looks poor.

The esp32 basic improvement is that it has two cores one dedicated to 
the WiFi so one does not have to "yield" to the WiFi code, it also has 
added hardware such as Bluetooth, but the Arduino interface was not 
ready as of earlier this week, and even if it was it's bound to be buggy 
and generate bad code, I still would have the same issues I have now.

Another angle at it is to use a different CPU for now that has a decent 
Arduino port and use it to tweak the software, then as the esp8266 port 
improves so will the running code, I have Arduino for MSP430, and PIC32 
and both have been around for a while.

Another angle is to adapt the software to C/C++, I have Rowley 
Associates C/C++ for ARM and work with that. I'll have to think about 
that, working with poor tools won't help much. Rowley has the advantage 
of awesome IDE, and excellent debugging tools, I have a Seeger JTAG 
interface to debug software with. I also have quite a few ARM boards 
with tons of FLASH and RAM. The more I think on it, this might be the 
way to go with tools that give one full control.
