- Fixed bug #61253: Wrappers opened with errors concurrency problem

#NOTE: There is a very small possibility that this will further break
#extensions that access wrapper->{err_stack, err_count}. On PECL SVN, rar is the
#only one and it may leak memory after this. I say "further break" because
#extensions that do that are already broken (will segfault) under ZTS, which is
#why this patch is necessary.
#There was what I deem as tacit acceptance from 5.3/5.4 RMs on this.
