I might be missing something obvious, but surely quite a lot of
code _does_ look like this, eg.,
StringBuffer foo = ...;
foo.append("Hello ");
foo.append("world");
or,
Vector bar = ...;
bar.add(something);
bar.add(somethingElse);
On the face of it these would be good candidates for synch block
fusion (assuming the synch couldn't be eliminated altogether
statically).
Cheers,
