# VM217 has a fixed 2GB pagefile; a 16-way MSVC parallel build of the
# heavy btc+NMC (and dgb+DOGE) TU set drives commit charge past the
# 32GB+2GB wall. The failure surfaces as an orphaned MSBuild with NO
# C####/LNK diagnostic. Cap MSBuild /maxcpucount (cmake -j -> /maxcpucount
# on the VS generator) to bound concurrent cl.exe and keep committed
# memory under the wall. Conservative 8; tune up only if headroom allows.
