Well.. my system is a: iP166, 24Mb RAM, 98Mb SWAP partition, 1.2Gb QF
EIDE, FH 1.0Gb SCSI-1 (on adaptec AHA-2940U) & Giga-Byte M/B.

The reason I mentioned it is because it is nearly as if it is reading the
whole directory structure (all mounted drives) as if I had done a 'find
/', I first experienced it in 2.0.29 and it can be unpredictable to
replicate, is it a bug?
