Yes and no. I agree I made a small mess. I'm not sure you have quite described how it should be.<br><br>I propose a few options:<br> 1 - asis, probably not<br> 2 - rename/merge ThreadUnsafe to ThreadInternal<br> 3 - move the part that external folks use, probably just MyId, to Thread, and then move ThreadUnsafe back to ThreadF, maybe ThreadInternal to ThreadF too<br><br>2 at least removes one interface that I added, reducing the three similar ThreadF, ThreadUnsafe, ThreadInternal, to just two, ThreadF and ThreadInternal<br><br>3 maybe gratuitously breaks folks but is a clean result<br><br> 4 - like you said, make all ThreadF users unsafe; but IF it is just MyId, and I'm not sure it is, which seems harmless, right? seems wrong to make them unsafe.<br><br> - Jay<br><br><hr id="EC_stopSpelling">From: hosking@cs.purdue.edu<br>To: jay.krell@cornell.edu<br>Date: Fri, 11 Sep 2009 16:51:11 -0400<br>CC: m3devel@elegosoft.com<br>Subject: Re: [M3devel] RC merge<br><br><div>Sorry, it looks like my commit failed last night because of need to merge with your ThreadUnsafe stuff.</div><div><br></div><div>FYI, we really should think about making ThreadF UNSAFE since anyone invoking on it is exposed to dangerous parts of the run-time system.
