Description

t4@iske:distributed-process $ ./dist/build/TestCH/TestCH
Basic features:
  Ping: [OK]
  Math: [OK]
  Timeout: [OK]
  Timeout0: [OK]
  SendToTerminated: [OK]
  TypedChannnels: [OK]
  MergeChannels: [Failed]
ERROR: thread blocked indefinitely in an MVar operation

This could be related to similar problems as issue #87 but I've not had time to investigate yet.

Research direction

Start by reproducing the failure with ./dist/build/TestCH/TestCH and focus on the MergeChannels test, which reports an indefinite MVar block. Compare the behavior with issue #87 and investigate why the failure is intermittent. Done means identifying and fixing the cause so MergeChannels completes reliably.
