Description Brady Eidson 2016-01-08 14:12:18 PST 
run-webkit-tests wedges forever when stderr has a very long line of output

Steps to reproduce:
1 - Build ToT WebKit
2 - Turn on IndexedDB logging in WebCore: `defaults write -g WebCoreLogging IndexedDB`
3 - `run-webkit-tests -1 imported/w3c/indexeddb/keyorder.htm`

run-webkit-tests will hang "forever", not even timing out the test.

python is using 100% CPU doing lots of symbol-less busywork.

The line of output is about 239k
