“hg convert” 期间系统调用中断

当我运行“hg convert”将 Subversion 存储库转换为 Mercurial 时，出现此错误：

fetching revision log for "/trunk" from 1538 to 0
run hg sink post-conversion action

    entry = pickle.load(self._stdout)
IOError: [Errno 4] Interrupted system call
abort: Interrupted system call

显然，可以重新开始读取，EINTR但我该怎么做呢pickle.load()？另外我想知道该信号来自哪里？我怀疑是 SIGCHILD，但不应该popen()处理它？

这似乎是 Mercurial 的一个错误。我不知道为什么它只骚扰我的安装。我的错误报告在这里：问题2196。

该漏洞随附有针对 Mercurial 1.6 的补丁。
