Attached patch patchSplinter Review
Sometimes I make a change to Nanojit which causes it to generates code that crashes.  When this happens I like to look at the generated code (TMFLAGS=assembly on TraceMonkey) and compare it with the generated code from a non-crashing version.  However, because LogControl prints to stdout, the output is buffered, and so when piping the output to a file sometimes part of the output is cut off because the crash occurred while the I/O buffer was partially full.  This makes it harder to diagnose the bug.

This patch flushes the I/O buffer after every line, thus avoiding this problem.
