Weave caches compiled code on disk, using cache keys derived from
the code string to be compiled. If compiled code is found from the
cache, no recompilation is done.

With network file systems,  I'm not sure how carefully locking is
implemented in Weave, so race conditions may exist if two processes
try to write the same code simultaneously.
