Description

将 workflow 移植到 qnx 平台，因 qnx 平台没有 epoll，打算改用 poll 替换 epoll，或者有更好的方案？正在阅读源码过程中，能否给予一些建议帮助？

Contributor guide

Research direction
Study the current epoll usage in workflow's I/O multiplexing layer, then design a poll based abstraction that can be conditionally compiled for QNX. Check the existing code for any poll usage. Test on QNX or using a poll emulation layer.
