That's true of the default pthread library on OpenBSD.  However,
I believe you can use the linuxthreads package on OpenBSD which
uses rfork() to create processes that share the address space,
file descriptors, etc, giving you the ability to overlap blocking
system calls.

FWIW, FreeBSD is in the same position: the default pthread library
provides entirely user-space threads, but linuxthreads is often
used to work around that.
