This is the top most wasteful Vector client after the other JSC stuff was fixed:

2680 vectors, 28.22KB used of 249.88KB, 221.66KB wasted at:

1   0x108917855 JSC::FunctionParameters::FunctionParameters(JSC::ParameterNode*)
2   0x10891793f JSC::FunctionBodyNode::finishParsing(JSC::SourceCode const&, JSC::ParameterNode*, JSC::Identifier const&)
3   0x108945704 JSC::ASTBuilder::createFunctionExpr(int, JSC::Identifier const*, JSC::FunctionBodyNode*, JSC::ParameterNode*, int, int, int, int)
4   0x10894459f JSC::ASTBuilder::Expression JSC::Parser<JSC::Lexer<unsigned short> >::parseMemberExpression<JSC::ASTBuilder>(JSC::ASTBuilder&)
5   0x10893c8a9 JSC::ASTBuilder::Expression JSC::Parser<JSC::Lexer<unsigned short> >::parseAssignmentExpression<JSC::ASTBuilder>(JSC::ASTBuilder&)
