Garbage Collection vs. Transactional Memory

Dan Grossman's paper "The Trasactional Memory / Garbage Collection Analogy" argues that

Transactional Memory is to shared-memory concurrency

as
Garbage Collection is to memory management

Here is a summarizing list of similiarities:

GC Term	TM Term
memory management	concurrency
dangling pointers	races
space exhaustion	deadlock
regions	locks
garbage collection	transactional memory
reachability	memory conflicts
nursery data	thread-local data
weak pointers	open nesting
I/O of pointers	I/O in trasactions
tracing	deferred update
automatic reference counting	direct update
conservative collection	false memory conflicts
real-time collection	obstruction freedom
liveness analysis	escape analysis

Be careful though: the analogy is a bad guide for studying TM. I believe we should first understand all the nuances and problems of implementing TM in its own right, and only then can we think of connections to Garbage Collection.
