[Bug]: apsi_test测试时，若接收方的数据量达到某一阈值程序会卡在某处，不执行也不终止 #148
Description
Describe the bug
首次在本地16G的mac上，执行项目中的psi/apsi/apsi_test.cc代码无误，但当我将TestParams{100, 100000, false}修改为TestParams{10000, 100000, false}后，程序会卡住，日志如下：

到上面最后一条日志就卡住了，此时本机内存情况也是正常的。
然后我更换了一台内存更大的电脑，TestParams{10000, 100000, false}能够顺利执行，但TestParams{100000, 100000, false}仍然会出现上述问题。此外，卡住之后不会大量占用内存和CPU。
Steps To Reproduce
运行命令 bazel run -c opt //psi/apsi:apsi_test
Expected behavior
期望修复该问题，接收方10000的查询数据，应该也不是很大。
