before closing debugger window in IDLE process.

debugger is active (15347); b) closing the debugger with the [X] button
(15348); and c) activating the debugger when already active (24455).
The patch by Mark Roseman does this by making two changes.
1. To suspend and resume the gui.interaction method, use the tcl vwait
mechanism interded for this purpose instead of root.mainloop & .quit.
2. In gui.run, allow any existing interaction to terminate first.

not to IDLE itself.

The underlying zlib library stores sizes in “unsigned int”. The corresponding
Python parameters are all sizes of buffers filled in by zlib, so it is okay
to reduce higher values to the UINT_MAX internal cap. OverflowError is still
raised for sizes that do not fit in Py_ssize_t.

Sizes are now limited to Py_ssize_t rather than unsigned long, because Python
byte strings cannot be larger than Py_ssize_t. Previously this could result
in a SystemError on 32-bit platforms.

This resolves a regression in the gzip module when reading more than UINT_MAX
or LONG_MAX bytes in one call, introduced by revision 62723172412c.
