I'd like to have rm being interrupted on SIGINTR. :-)
Solaris has a nice feature called "delayed I/O". The corresponding
IOCTLs are `_FIOGDIO' (for status query) and `_FIOGDIO' (for setting
"0" or "1", fast or slow repectively). This speeds up removal of
directory trees drastically. As usual, there is no documentation on
it, except for the remark "WARNING - the support for these ioctls may
be withdrawn in future OS releases." in /usr/include/sys/filio.h.
Dunno exactly, what it does, maybe just what it says. It would
probably delay the I/O for that further data can be accumulated.

Dunno who wrote it, but it was some guy from Sun in his spare time.
