To start with:

$ stap -p4 --dyninst -m hello -e 'probe begin { println("hello") exit() }'
hello.so
$ ./oc-inject --stapdyn myapp-zrblm -- hello.so <arguments to hello.so>

But ideally, this should be doable with one command, rather than needing to manually compile an .so.

Known problem TODO: currently, caching will assume that .so's with the
same name are unchanged. This makes sense for system libraries but not
for .so's generated by stapdyn. Fix by checksumming the contents of
stapdyn modules.
