At the current state of the code the deadlock is not achievable,
but if 'bufferedAmountLowThreshold' and 'maxBufferedAmount' were to
get changed up, it could happen.
Example: If 'bufferedAmountLowThreshold = 1024',
'maxBufferedAmount = 1280', then if a message of len 999 is sent,
'BufferedAmount()' could return '999', and the condition would still
evaluate to 'true' (999 + 999 > 1280).
Since 'bufferedAmountLowThreshold' was never exceeded, the
'OnBufferedAmountLow' event would never fire, so we're stuck.
Use wasm_exec.js in GOROOT to ensure that the wasm file be loaded,
there is no need to use a specific version of go to build wasm,
and delete vendor-wasm.
