Comment:
My branch `bug21943_029` fixes this, I believe. I think the reason we
haven't run into this before is that most getpid() callers on Linux use
the vdso version of getpid() rather than the syscall. I don't know why
this particular version of openssl is doing the syscall instead, but the
patch should fix it.
Possible backport.
