- Each isolate starts off with a 'Default' UserTag set.
- A null tag cannot be set.
- Calls to clearCurrentTag() should be replaced with a call to UserTag.defaultTag.makeCurrent().
- makeCurrent returns the previously current tag.
This allows for the following pattern to work:
callee() {
var old = calleeTag.makeCurrent();
...
old.makeCurrent();
}
caller() {
var old = callerTag.makeCurrent();
...
callee();
assert(getCurrentTag() == callerTag);
...
old.makeCurrent();
}
