How to iterate over a SharedTable?

[mrhdias]

I need to know the keys and values that are being inserted in a sahred table. 
The table is populated by a multi threaded application.
    
    
    import sharedtables
    
    var table: SharedTable[string, string]
    init(table)
    
    table["a"] = "x"
    table["b"] = "y"
    table["c"] = "z"
    
    # To do this I need to know the keys. But I don't know them in advance.
    echo "a ", table.mget("a")
    echo "b ", table.mget("b")
    echo "c ", table.mget("c")
    
    # My Problem: How to make this work??
    for k, v in table.pairs:
      echo $k, " ", $v
    
    
    Run
