[gentoo-portage-dev] EbuildProcess logs poll-error to already removed $T (on AIX)

[Michael Haubenwallner]

Hi Zac (et al),

while this problem occurs on AIX only (for now?), I doubt this problem is
introduced in prefix-portage.

With recent prefix-portage-2.2.01.18125 (Fabian, how do you calculate the
version numbers since moving to git?), the "EbuildProcess" spits this
every now and then during "emerge mime-types" fex:

 * EbuildProcess received strange poll event: 16384

While I don't understand (yet) why this is there on AIX at all, it does
trigger an IOError when trying to log this message to $T/build.log after
$WORKDIR has been cleaned up. When I avoid the logging of this message,
everything (seems to) work fine.

For the attached logfile, I've added these two lines to usr/lib/portage/bin/ebuild.sh:

Any idea?

Thank you!
