Yeah, it's supposed to work. I'll look into it.

Hi,

Is BPatch::getNotificationFD() still supported in Dyninst 8.0?  I mean
for Linux, since it's implemented "#if !defined(os_windows)".  I get a
proper-looking FD, but polling on it blocks indefinitely.

The only signalNotificationFD() call I can find is in BPatch
registerUnloadedModule().  That one looks like it might actually be
vestigial, and the correct call was in pcEventHandler.C, until this
commit removed it:

     Bugfixes in Dyninst/ProcControl integration on Windows.
     Untested on other platforms.

So I guess this functionality falls under that "untested" blanket...

Thanks,
Josh
