Seems like they're not handling EINTR for some syscalls. I remember when I was first learning Unix programming, and read about this stuff about signals and EINTR, I was baffled how much of a steaming pile of crap Unices are. Later learning about the inability to do truly non-blocking I/O was another similar moment.
