UIOP:RUN-PROGRAM itself is synchronous only, but its internal
UIOP::%RUN-PROGRAM is asynchronous on platforms that support it...
which does not include ABCL at this time, but does include CCL and SBCL.
The interface is under-documented, and which exact subset of features
it supports depends on the underlying implementation;
but obviously it works well enough to portably implement the synchronous
UIOP:RUN-PROGRAM.

I'll update the docstrings.

If you only care about CCL and SBCL, you can use UIOP::%RUN-PROGRAM.

If you want a portable solution that requires an external library, try
IOLIB/OS:CREATE-PROCESS.
