Unfortunately V8 has a debug-only assert that checks
that a SnapshotCreator actually created a snapshot:
7d8c9aa769/v8/src/api.cc (L571)
This was not being triggered in Linux & Mac debug builds
because we were using the prebuilt release V8 build.
It was being triggered in Windows debug build because there is
a prebuilt v8_debug.lib. However the Windows error went unnoticed
because we only run release builds in CI.
This was introduced because Tokio would swallow panics. This is still
the case, but this panic handler causes more problems than it solves.
It requires people to know how to use debuggers to inspect stacktraces.
TODO:
- Fix Tokio to not swallow errors.
- Be vigilant in the intrim to not introduce broken tests due to this
unfortunate "feature" of tokio.
This is more optimial and this fixes a problem where occasionally
remove_and_symlink will error with:
gen/compiler_bundle/main.js --sourcemapFile /Users/rld/src/deno --silent
Traceback (most recent call last):

- Don't crash when .mime file not exist in cache (#1291)
- Process source maps in Rust instead of JS (#1280)
- Use alternate TextEncoder/TextDecoder implementation (#1281)
- Upgrade flatbuffers to 80d148
- Fix memory leaks (#1265, #1275)
- Improves speed and binary size significantly.
- Makes deno_last_exception() output a JSON structure.
- Isolate::execute and Isolate::event_loop now return
structured, mapped JSError objects on errors.
- Removes libdeno functions:
libdeno.setGlobalErrorHandler()
libdeno.setPromiseRejectHandler()
libdeno.setPromiseErrorExaminer()
In collaboration with Ryan Dahl.
