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.
