goschedviz - v0.0.6 - Thread Count Fix

v0.0.6 - Thread Count Fix

What's New

• Fixed thread count visualization for programs using stdin:
  • Now correctly shows actual thread count when monitoring programs that block on stdin
  • Passed through real terminal stdin instead of pipes

Details

• Updated collector to use real stdin for monitored programs
• Fixed thread count reporting for blocking I/O operations

This release fixes thread count reporting accuracy for programs that use blocking stdin operations, ensuring correct visualization of system resource usage.
