yaml.load appears to be really (really) slow on large input. My string is

--- seqno : 1 outof : 1 result :

• <1.6Mbyte string>

Both the input and output are fairly simple. Why does it take a long time to parse?

When parsing the following: terminator : "\n\n"

The value of the right side scalar is returned as \n, rather than \n\n. Likewise, four newlines ("\n\n\n\n") is parsed as three ("\n\n\n").
