EspruinoWifi: V1.94 - New interpreter error: FIFO_FULL

Hi Gordon

I noticed that i get from time to time the following error in the console on the EspruinoWifi:

"New interpreter error: FIFO_FULL"

It happens, when i send socket data (small junk of JSON data) after a setWatch of a button is triggered.

It is very difficult to reproduce.

• process.memory shows more than 3500 free mem after the error
  
• I think it never happens when i send data triggered by setTimeout or setInterval
  
• It happens very rarely
  
• It seams to be that it happens only after powerup, triggered by one of the first setWatches but well after the board is wifi connected.
  
• After the error, everything is working as expected with additional setWatches and socket transfers.
  
  

I use the following pins with setWatch:

A1, A5, A6, A7, B9, B8, B4

I think it's not dedicated to a special pin i used.

Greetings
