Golang cmd.Start () иногда висит на предохранителе

Похоже на какую-то магическую проблему времени. Я заметил, что startProcess () в os / exec_posix.go выполняет вызов Stat (), поэтому я сам выполнил Stat () перед вызовом Start (), и проблема, похоже, ушла (или стала меньше, чем 1/1000 ).

Редактировать: Все еще происходит, просто реже. След стека от того, когда он висит:
