CodeAbra/iai-mcp v0.4.1 fixes GIL contention between REM cycles and MCP requests that prevented memory_recall timeouts. The _tick_body now yields the REM loop on mcp_socket activity.

Why it matters: Upgrade to v0.4.1 if memory_recall operations are timing out due to concurrent REM cycle and MCP request activity.

Summary

AI summary

Fixed GIL contention between REM cycles and MCP requests preventing memory_recall timeouts.

Full changelog

What's changed

Fixed

GIL contention between REM cycles and MCP requests: _tick_body now yields the REM loop when mcp_socket reports active connections or recent activity, preventing memory_recall timeouts during long consolidation runs.
INTERRUPT_RECENT_ACTIVITY_WINDOW_SEC promoted to module scope (was duplicated as a local inside main()).

Added

IAI_MCP_SESSION_CAPTURE_CLI env var for developer-override of the CLI binary path in the session-capture hook.
2 regression tests for the MCP-yield branch.
