stress test discovers text rendering slowdown issues

[richardanaya]

I developed a rather simple app that just prints random colored @ symbols again and again. There appears to be two bugs.

• the text render speed is rather slow
• the text render speed gets slower and slower as time goes on

running this with wasmer has no problems at a consistent 12ish ms per frame

I wonder if this is related to #11

I don't believe this is relevant now that wasmer.sh uses xterm.js for rendering and is wired up to Bash compiled for WASIX. Feel free to re-open this issue if it is present with the new @wasmer/sdk package.
