Interrupted system call on open

[Michael Sperber [Mr. Preprocessor]]

Thanks for the patch fixing command-line handling.  Now, for the
actual problem:

I get interrupted calls to open(3) on 0.27/FreeBSD 3.2-RELEASE.  This
seems to happen only with certain applications (so far, Window Maker,
Netscape, and building Scheme 48), but I can't see anything unusual in
the code they use.  With these applications, it happens fairly (but
not entirely) consistently, so it's reproducible, to all intents and
purposes.

The logs are not very illuminating.  The arladebug log just says this:
