Deferred logger messages accumulate
ResetBuildState() only resets parser state:
XMake.cs#L1498-L1505.
The static deferred-message list is retained:
XMake.cs#L1525-L1529.
Terminal-logger/environment decisions append messages every invocation:
XMake.cs#L2764-L2795,
#L2861-L2882.
Later builds copy the complete retained list:
XMake.cs#L2020-L2055.
This can create stale/duplicate diagnostics and unbounded list growth during server reuse.
Process priority is not restored
/lowPriority lowers the current server process:
XMake.cs#L2462-L2484.
A later normal request initializes its local lowPriority flag to false but never restores the server process to normal priority.
Suggested direction
Create an explicit per-request reset boundary covering all non-cache mutable state. Cache retention should be deliberate and separately enumerated.
