Comment (by guest):

 At least the eventfd part of this seems to be a bug in glibc, when used
 with an older linux kernel version, such as 2.6.32. See this bug report
 I've filed on that: <http://bugs.debian.org/715212>

 I am unsure if the pattern match failure is being caused by the eventfd
 failure, or is unrelated.
 I have seen a program only show the pattern match failure, while a
 different program first prints the eventfd error message before failing
 due to the pattern match failure.
