As mentioned above, libonyx uses thread suspension and resumption to
implement garbage collection. This has the side-effect of making restarted
interrupted system calls a real possibility. However, the operating system will
return with a partial result if the system call was partially complete when it
was interrupted. In practice, what this means is that short reads and writes
are possible where they otherwise wouldn't happen, so the application should not
make any assumptions about interruptible system calls always completing with a
full result. See the thd class documentation for
more details.
