Using ProfMonitor or ProfMonitorTree >> monitorBlock: to monitor Smalltalk execution creates a file gem_pid_nnnnnn.pro in the home directory of the user (for an RPC login), or in the working directory for a linked login. This file is not being removed after the report is returned. Large profiles files may use a considerable amount of disk space.
After profiling is complete, manually delete these .pro files files.
