I went into joshua/decoder/chart_parser/ComputeNodeResult; adding and
removing the following lines makes a huge difference in speed. So it looks like
logging is neither (a) time-safe nor (b) thread-safe.
Or that something is wrong. I can't get the decoder to output any
statements using the logging properties. It's sort of a pain to have to rebuild
a tarball every time you want to test something...
FYI, I won't have any more time to spend on this before Tuesday.
```
if (LOG.isDebugEnabled()) {
LOG.debug("ComputeNodeResult():");
LOG.debug("-> RULE {}", rule);
}
[snip]
if (LOG.isDebugEnabled()) {
LOG.debug("-> item.bestedge: {}", item);
LOG.debug("-> TAIL NODE {}", item);
}
```
