- GDB inferior may be suspended while the inferior grabs mutex. This causes deadlock in terminal I/O. With this patch, timeout for waiting mutex is set to 0 for the debugger process when the process calls CreateProcess() with DEBUG_PROCESS flag to avoid deadlock. This may cause the race issue in GDB, however, there is no other way than that. Addresses: https://cygwin.com/pipermail/cygwin-developers/2021-December/012542.html
