Ethan Atkins 0d2b00c7e9 Cache jar classpath entries between commands
Zinc frequently needs to check the library classpath to ensure that
class names are defined in a given jar. There is a cost to looking up
the class names in the jar so it's a benefit to cache this across runs
so that we don't have to redo the same work every time. More
importantly, in testing with the latest sbt HEAD, I found that sbt would
crash fairly frequently because it ran out of direct memory, which is
used by nio to read and write to native memory without copying. The
direct memory area is shared with the java heap and if it reaches the
limit, the jvm crashes hard as though kill -9 was invoked. After caching
the entries, I stopped seeing crashes.
