Race Condition

[mchlswyr]

Hello,

This is the pull request for 389 on Piazza. Some things to note:

• I removed out2 in the first L23 example as it caused the assertion to fail.
• I updated all examples (I think) to use StreamFlags::DEFAULT.
• I did not update notebook. Is there a script that does this, or should I copy-paste from L23.tex?
• I did not recompile. My environment's not set up to compile, but I'm assuming yours is.

Also, if you want to verify for yourself that there is a race condition in the examples, you can try changing the DeviceBuffer sizes to something very large. I was able to reproduce the race condition in the first example from lecture 23 as follows:

1. Login on ecetesla1;
2. Change the DeviceBuffer sizes from 10 to 102400;
3. Run the following until the assertion fails:

   cargo build --release
   while true; do
   ./target/release/mybin
   done

4. If it doesn't fail after a couple of seconds, goto 2 and increase the size.

Please let me know if I should add, remove, or update anything. Thanks!

Thanks! Yes, we have scripts that automatically compile and compile the notebook.
