MPS issue job001357

TitleConfigura cannot use Win32 fibers
Assigned userRichard Brooksby
DescriptionThe MPS does not support Win32 fibers. Using the stack of a
Win32 fiber to store roots will not work. Either the MPS will
not scan the root or it could crash trying to scan the root.
Analysis2006-03-20 drj:

There is no way for an MPS client to specify that a fiber stack
should be registered as a root. Attempting to use the mps_thr_t
type and mps_root_create_reg will not work because the MPS is
not "fiber aware" and will not use the correct value for the top
(most accessible) of stack for a fiber. See my mail message
[1], for my original analysis.

See [2] for an overview of Win32 fibers.

In addition, other platforms may support something analagous to
Win32 fibers. They won't work either.
