This is the culprit. People that have this file don't have the problem.
If this one goes wrong, the errno value remains there, and the next
decision that bases itself on linuxerror goes wrong.
This is why it was hard to reproduce:
In my case, this happens
getpid() = 3953
readlink("/proc/3953/exe", "/export/home/marcov/pipetest", 255) = 28
open("/etc/timezone", O_RDONLY) = -1 ENOENT (No such file or directory)
-> failed
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=1074, ...}) = 0
open("/etc/localtime", O_RDONLY) = 3
-> found, but errno is untouched.
