The test has some exit commands:
```
"exitCommands": [
"?settings set target.show-hex-variable-values-with-leading-zeroes false",
"settings set target.show-hex-variable-values-with-leading-zeroes true"
],
"stopCommands": [
"?settings set target.show-hex-variable-values-with-leading-zeroes false",
"settings set target.show-hex-variable-values-with-leading-zeroes true"
],
"terminateCommands": [
"?settings set target.show-hex-variable-values-with-leading-zeroes false",
"settings set target.show-hex-variable-values-with-leading-zeroes true"
]
```
The test case itself passes, but tear down occasionally fails because we fail to get a `disconnect` response back. The DAP log shows this crash causing the dap server to shutdown before it can respond to the disconnect:

Aside: the buildbots do not enable this DAP logging, which would make debugging buildbot errors much easier.
