For portability reasons, Mono uses Win32 APIs for I/O and related
operations (semaphores, process creation, etc). You can find the Unix
versions of these Win32 APIs in mono/mono/io-layer.
So on Windows, Mono directly uses Win32, while on Unix Mono uses Win32
APIs implemented in the io-layer.
This was necessary because many of the System.IO, etc. APIs have
"Win32-isms" which prevent direct Unix implementation.
Part of the wapi implementation is per-user shared-data. This holds
process IDs of mono processes, file share information (so opening a file
opened for exclusive read can be denied), and other assorted
Deleting this shared data can have bad effects on mono applications. :-)
