<para>Kernel's unit of execution flow is a thread. A thread is an entity |
that executes code and has a stack that takes up some space in memory. The |
relation between kernel and userspace threads is 1:1:n, meaning that there |
can be several pseudo threads running within one userspace thread that |
can be several so called fibrils running within one userspace thread that |
maps to one kernel thread. Threads are grouped into tasks by functionality |
they provide (i.e. several threads implement functionality of one task). |
