+* reimplement the fast-path of the nursery allocations in the GC
+** use this for frame allocation in stmrewrite for call_assembler
+* use specialized barriers in JIT
+* optimize produced assembler code
+* avoid calling aroundstate.after() for call_release_gil and instead
+  start a normal transaction after the call
+* maybe GUARD_NOT_INEVITABLE after call_may_force, call_assembler
+  which is a small check if we are inevitable and does a transaction_break
+  if we are.
+* look at XXXs for STM everywhere
