I was under the impression that, because user thread scheduling is done
in user mode, a thread that goes to sleep calling a blocking read()
system call will put the entire process to sleep until that read()
returns (and so all user threads in the process will also be blocked).
Is this correct?
If it is, it sounds like a user thread implementation would be bad for
Mr. Keahan's application, and something like the LinuxThreads port might
be more appropriate.

Please correct me if I am wrong.
