Public bug reported:
[Impact]
There is a rare case that fcitx runs at 100% CPU when using Sogou Pinyin
input method that sometimes happen after suspend/resume, even though the
problem does not break client usages, it will drain battery of laptop
and makes fan very noisy.
[Test Case]
After upgrading the package, user will not see 100% CPU usage of fcitx after
frequent suspend/resume.
[Regression Potential]
The patch limits the call of accept() to be less than 21 times, and the calling
code already has error handling when the returning value is less than 0, so the
possibility of regression is minimal.
