Module Name:
ntldr.h
Abstract:
This module implements the public interfaces of the Loader (Ldr)
subsystem. Ldr is coupled with the session manager. It is not
a separate process.

//
// 13-Nov-2000 jonwis: This 4k buffer caused several stack overflows in a
// stress run. There's a stack-local instance of this in
// CsrBasepSxsCreateResourceStream, which was blowing the stack in
// CsrBasepSxsCreateProcess, so this has been toned down to 1024
// bytes instead. The counter-argument is that LdrCreateOutOfProcessImage
// has its minimal cross-process read size set to 4096 bytes, and always
// does an RtlEnsureBufferSize to make sure it's 4096 bytes. We could
// just as easily get rid of this storage space and always have the
// loader create a heap-space buffer instead, and avoid any stack usage
// whatsoever.
//
// 17-Nov-2000 jonwis: The executive decision has been made (on a suggestion by
// mgrier) to reduce the size of the PreallocatedHeadersBuffer to a
// single byte. This way, we always take the hit of allocating space for
// it, but we don't use any (or much) stack space and don't explode in stress.
