Common-Description:
 nPth is a library to provide the GNU Pth API and thus a non-preemptive threads
 implementation.
 .
 In contrast to GNU Pth it is based on the system's standard threads
 implementation.  This allows the use of libraries which are not compatible to
 GNU Pth.  Experience with a Windows Pth emulation showed that this is a solid
 way to provide a co-routine based framework.
