I suppose you could copy the API from CCL or SBCL, both of which are
reasonably complete, and IIUC, portably implemented on both Windows
and Unix at least for CCL. CMUCL and SCL have something similar, too -
for good historical reasons. If it makes sense, I'd like also a
:directory argument, but that's relatively secondary.

I don't know if it makes sense wrt the underlying JVM API, but another
different approach would be to expose posix_spawn - except that its
libc implementation seems somewhat broken, so obviously no one is
using it too seriously. Libfixposix reimplements it and iolib uses it
to build its create-process abstraction that I'm working on refining.
I don't know how much sense this makes on Windows or on the JVM API,
though. But if you're interested, you should discuss with me and/or
Stelian as we're trying to settle on an API for IOLib.

I disrecommend the APIs from Allegro, CLISP, ECL, GCL, Lispworks, XCL.
