Transactions

[littledan]

The concept of a "transaction" models a sort of fork of the universe, where a (potentially asynchronous) series of writes and reads occurs before "committing" the writes to the main signal graph. Transactions are important for modeling React Suspense-style transitions, and things get especially complicated when multiple transactions can be pending at once (but may be committed separately). We haven't even worked out exactly what the semantics or should be, but @shaylew and @trueadm have been investigating/prototyping in this area. One important result to look for: whether transactions can be modeled on simpler signal primitives, or need built-in support to work well.

What am I doing, I already filed #73 for this.
