[Xen-devel] [PATCH v2 0/3] libxl: event system: SIGCHLD related fixes

libxl's SIGCHLD handler is broken if libxl_sigchld_owner_libxl_always
and does not always work correctly with the fd registration system.

 1/3 libxl: event system: pass gc, not just ctx, to internal
 2/3 libxl: event system: Make
 3/3 libxl: event system: properly register the SIGCHLD

This is v2 of this series because when I reviewed it myself I found
that there was a critical missing ! in perhaps_removehandler, which
would remove the handler iff it was needed.  IMO this shows the
weakness of my testing arrangements.

I'd really appreciate some feedback on this from Bamvor or Jim.
